The Copper alloy Bullet and the leaded Brass 56 mm Bullets differ in Material. While the Copper alloy weighs 8,9 g/cm² the leaded Brass is with 8,45 g/cm³ slightly lighter. with equivalent Shape the heavier one has BC0,95 while the lighter on has BC 0,9. This means the Copper alloy Performance bullet will against the Wind shoot not worse than a .50 BMG with the Hornady A-Max. The leaded Brass version will be cheaper and only slightly less performing, so a real good Value for the Money.

The unique aerodynamic Design (Minimum Drag Nose), low friction Drive Bands that consequently allow to upload  within safe Pressure limits to faster Speeds that both Bullets are believed to outshoot anything currently commercially on the Market in windy Conditions. Such detailed ballistic Predictions have been made for an existing Bullet line, see Kupferjagdgeschoß, an practical Results agreed well with Theory, so we have no Doubt to score once more.

Lutz,

the only one that can compete is the 112.5 mm copper-alloy. The information I need to provide to those who wish to purchase the bullet is:

What were my personal experience with it at 100 meters? LM: Shoot them to know!

Bullet type? LM: Haack Minimum Drag Nose!

Bullet weight? LM: .408" Copper alloy bullet, 56 mm long, 27,15 g heavy, BC 0,95!

Case type? LM: Dieter Horneber

Powder? LM: Try PB Clermont PCL 517 dense double based Powders from Belgium! US market distributed through WESTERN POWDERS Inc. MT www.westernpowders.com

Primers? LM: CCI Large Rifle Magnum!

Seating depth's? LM: between 112,5 and 113 mm!

When signs of pressure first appear on cases? LM: Above are maximum Loads!

Maximum load capacity? LM: Load Density in % is given in the Tables!

Velocity of that load? LM: Read the Tables.

Which load grouped .5 MOA or less with the highest velocity. LM: First load and shoot the Laddertest to find the least sensitive Loads! LM: Troy, Your Task!

Then to 914.4 meters then to 1605 meters then to 1828 and so on until the groups start to dramatically expand and become ineffective for soft targets 660 mm groups. LM: Troy, Your Task!

At this point i will have a witness "Blaine", and proven statistics for the bullet with the Ballistic Computer models as well.

I also corresponded with the http://www.precisionworkbench.com/ owner about new, more realistic computer software for palm heal ballistic devises. I arranged to go shooting up to 2000 meters for extreme range long (ELR) data, he  recently was unable to acquire. I will ask him to accompany me or make his own way to Raton, NM to market his product there, as well as gain test results from the match with the new bullet design.

Did you get the specifications from actual tests or from a Ballistics Program? LM: All Data presented are calculated, either by commercial CAD-Programs or own Software. Up to now i designed some 20 Bullets and so far Experience tells, my Models and Programs fit well.

The Airdrag (deutsch Luftwiderstand) stems from 1974 Robert McCoy Program in Basic, adapted into JavaScript to run on the Web. The Bullet flight (deutsch Außenballistik) is again a JavaScript Program for the Web, written after Siacci's and d'Antonio's Mathematics from 1834 with recent Refinements by Arthur Pejsa. See more on C_w(v).

Read an Explanation here http://www.precisionworkbench.com/4.htm, who uses the same Approach.

Michael Reifenberger ported it in a rudimentary Version for handheld Devices with SuperWaba. You find him and BalCal on https://www.reifenberger.com.

My exterior Ballistics Airdrag have serious Program flaws below 425 m/s, so use them not below! While i could fix that, i never saw the Necessity, as all Bullets then already fall like a Stone out of the Sky. The hamd held Version could also be finished, if needed. Obviously Blaine L. Fields / Lex Talus Corporation uses the same Approach and his Software is probably much User friendlier, so i recommend to try it.
 

If so what was the finished Bullet weight? LM: As stated in the Tables above,

Ballistic Prediction

Troy,

with the above outlined Tool set plus Hartmut Brömels Interior Ballistic Program QuickLoad and Cartridge Design Program QuickDesign plus an Understanding of the Work of these Men,

Ludwig Prandtl / Freising Germany early 20th Century found Fluid mechanics. Upon his Work are all others based. If one had studies his Work then, Terminal Ballistics would have advanced then too.	Prandtls Götting Student, Theodore von Kármán /  Hungary, calculated already in the 20ties first the Minimum Drag Nose for a Bullet.	The Hamburger Max Munk calculated slender Bullet Moment derivations at small Inclination Angles. Beat Kneubühl / in Thun later proceeded to find the longest spin stabilized Bullet. B. K. Report is available per FTP or Email upon Request  (auf deutsch hier).	Wolfgang Haack / Berlin expanded Kármáns Work. In Peenemünde he published (secret within the Wehrmacht) 1941 a closed analytical Solution for the Minimum Drag Bullet. I use his Mathematics to shape performance critical Bullets, like .408" Chey Tac Möller

any Physicist can design Cartridges and Bullets from Scratch and predict their Performance, as i do. The Art is in these Days much further advanced, but to get the Ground work right, such Tools work well. With good Gun Smiths Craftmanship like from EDM Arms and fine Tools like from David Manson Precision Reamers, a Gildemeister CNC-Lathe, sound Advice on Alloys Kupferinstitut, a dependably Copper Refinery to deliver quality Metals for the Automats, a good Result on the first Go was proven on more than 20 Bullet designs on the first Flight; and this includes Terminal Ballistics on Hunt bullets. No Miss so far, Bench rest stuff included!

So to say the Bullet Design and Fabrication process is understood is no Stretch or even ,,Magic", but day to day Work. If You state a Goal, i shall find a Solution (if exits) to deliver Product within short Time (Weeks). It's not cheap, but predictable. So you get stated Performance right away, not just Stuff to play or simply waste Resources. That's the Difference between an engineered Product and a Piece of Metal!

Lutz Möller,

Lutz,

Blaine cannot go to Raton, we are shooting the 3^rd week in July for the ballistics software. The Fifty Caliber Shooter Association is strongly objects to fire other calibers then .50 at the match. We planned to shooting Thursday and Friday before the match. I have already been warned not to.

Troy, Sonntag, 6. Juni 2004 01:42

Lutz,

Good to hear from you again.  I am keeping track of your efforts through Troy and hope you can get the product here for testing. I was sorry to hear the price has escalated from 1.65 estimate to almost 3 US dollars.

LM: I always quoted between 2 and 2,1 €. With 1,22 $/€ Exchange rate, that amounts 2,44 to 2,56 USD + Freight. So I never increased the Price. You mix the Price for the big 56 mm long and 27 g heavy Bullet, with smaller Hunt bullets in the 30 Millimeter Range and around 10 g. Those are 1,3 € or 1,59 $. The Length increases Machine time and when the Noses become very slender, machining must slow down. Therefore the big (.40" and .50" Cal. Performance Bullets are and will always be expensive.

So If this is true, its capability would not matter because no one could afford to shoot it but militaries or hit men!

I also hope your larger Bullet becomes possible. The other version with a lead and bronze allow does not sound very appealing. I refuse to shoot Lost River Bullets anymore because of severe fowling of what I guess to be Bronze and Nickel.

I am relatively happy with the Barnes 421.4 grain all copper bullets newly available.

LM: I have no Information about that Bullet so far. Please send me a Picture and tell me the Price!

I am in course in touch with the same small community as you including EDM Arms.

I wonder how you can project a BC for the larger bullet without any being fired?

LM: Read Ballistic Prediction. The Art is not new and currently much more advanced, than stated above. 

Randy Cullinan, Sonntag, 6. Juni 2004 04:46

Barnes

Ty,

would you please be so kind, to send me some Information about the further down mentioned Barnes .408" grain bullets newly available.

A Picture and a recommended Sales Price would help.

Sincerely, Lutz, Sunday, June 06, 2004 4:28 AM

Hi Lutz

Thanks for the email. Recently I have been in contact with Randy Cullinan. We have quoted him pricing on our all Brass bullets. It is as follows. We are going to do a limited run and are pricing them at $24 per box of 20. We are also offering a 10% discount for orders over 500. They will be .408 diameter and will weigh 419 grains. They are similar in design to the .510 cal Long Range Solids that we currently hold the world record with.

I attached a page from our catalog that will show some photos of the 50BMG Long Range Solids that look similar to the 408 Chey-Tac 419gr that we are offering. The bottom row will give the closest resemblance. If you have any other questions or would like to place an order, you can call me at the toll free number below.

We Aim to please. Reloading is a great hobby, enjoy it!

Ty,

please look at this Page. You know, Competition is more Fun (read the old Pin ball machines).

Sincerely, Lutz, 9^th June 2004

Good to hear from you again Lutz.

You are correct, a little competition is more fun and good advertisement for the sport. To answer your other questions, the 419gr .408 cal Barnes Monolithic Brass Solid is 2.133" (54,18 mm) with a canular ring and preliminary 300 yd tests show a true BC of .850. Thanks for the great questions.

Ty Herring, Mittwoch, 9. Juni 2004 23:23

Lutz

I will have to cancel my order. No one will buy the bullets. I fell strongly, they will work, due to their design, but they are not applicable at that cost. For me, to continue to research, the actual results would be of personal financial cost to me and not advance the availability of bullets within reasonable cost for others.  I can purchase 50 bullets from whoever pays for the entire run of bullets and would be happy to send you the results of the bullets behavior after personally firing the bullet. My apologies for the outcome, but i am still willing to shoot your bullets for actual results from my rifles.
 
With Kindest Regards,  Troy, Freitag, 11. Juni 2004 23:38

Troy,

at least you finally say, what you mean, unlike others, who just to stopped to communicate.

When Ty Herring / Barnes offered a limited Run .408" Bullets with tentative .85 BC @ 1,20$ / Piece in 20 Piece Boxes, the Air to breathe thinned out. I have no Idea, how real his Prices relate to real Cost, but an Offer is an Offer and, if shipped, must be taken serious.

The leaded .408" Brass bullet will, as far as I can predict, still outperform the 419 Grainer from Barnes, not to mention Lost River 419 grs. "High Pressure Fouwler". With 398 Grain and a higher BC (0.9) than all other available, the Haack Minimum Drag Design will initially fly faster and on its Journey stay faster than the others. That translates to a longer useful Range! Therefore a premium Price is in Order, I would suggest.But I get Your Point, only so much Premium will be paid for some, let's call 10% Advantage. That Premium is probably not 100%.

So let me come back to You and Corbin on the leaded Brass Price later. Your request is not forgotten. Ken Johnson from K&P Handguns suggested to research stream caste Lead Bearing Bronze, as a Bullet Material and we will.

I know I can design aerodynamically superior Bullets for Hunters, to those Cost concerns not really, but to do the Trick for Sport shooters, using many more Bullets and therefore are much more exposed to Bullet cost is another Challenge. Let's see, if I can find a Solution.

Sincerely, Lutz

Ok Lutz,

Thank you for all your time and effort. I am still interested if the cost gets closer to $2 U.S. per bullet.

With Kindest Regards, Troy, Samstag, 12. Juni 2004 05:27

Troy,

let me see what we can do. You once mentioned 30.000 Bullets. How did guessed that Number? 300 Rifles by 100 Bullets are 30.000. That Volume and Price would fit, but made on another Multi Spindel Machine we not currently have. That would produce 1 500 000 Bullets a Year. Now i wonder, how to sell that Volume. So currently I design a full Sport bullet line, see ,,Kupfersportgeschosse" and also talk to the Imperial F-Class Folks, who need Stuff under 8 mm with some other Restrictions on Speed an BC Combination to actually shoot long Range buts still limit the Bullets maximum Range, rather interesting Combination to get all Players on a leveled Field, but not to be too restrictive on technical Solutions.

Peter Jackson / http://www.jacksonrifles.com/ is on of the better Shooters i know, he holds also a Record, read http://www.jacksonrifles.com He also scores well in the F-Class as well as in Bisley, even with silenced Guns, much to the Astonishment of some Spectators. He introduced me to long Range shooting and Ballistics. You find his limited d'Antonio-Pejsa exterior Ballistics there too. For Simplicity i just mirror his Page http://www.jacksonrifles.com/ballistics.htm here below

External ballistics

To calculate elevation and windage for long-range hunting and target practice, we developed this MS Excel spreadsheet: pejsa ballistics.xls, which provides a bullet trajectory table in scope MOA. Revised 29 January 2001 to show time of flight and to warn of sub-sonic or trans-sonic bullet speed. Also available as a compressed file: excelbal.zip (9 kb).

For field use, this spreadsheet will print a small MOA trajectory and windage table to stick on a gunstock. For techno-junkies, the spreadsheet will run on a WindowsCE or Psion hand-held computer so you can adjust for atmospheric conditions, wind speed, etc. in the field. For use with a rangefinder, the spreadsheet can be used to calculate windage and elevation MOA for any particular range in addition to the usual tabular output.

Methods and formulae used in this spreadsheet were developed by Prof. Arthur J Pejsa, http://www.pejsa.com/

Internal Ballistics

WinLoad/Wingyro is a useful free program, written by Bisley gunsmith John Knight. It does internal ballistics and bullet stability/rifling twist calculations.

Home

Peter, Hugh Forgie and i started to shoot us warm in Dumfries Galloway hills on some Varmints, i.e. Rabbits, the Sheep farmers hate, because the Sheep brake their Legs in the Rabbit holes. I had no Idea about shooting in the Wind then, but close to the Atlantic the Wind blows, i tell you as a Sailor! Not the soft Breezes from the Baltic pool but with the big Lungs from the endless Ocean. So with his Advice on Windage and actual Scope Setting i was able to willingly shoot young Rabbits on the Shoulder blade on 200 m with one of the Rifles he built in .243 Ackley and the Hornady A-Max. We quickly calculate the allowable Error on that Target 3 x 3 cm:

My regular Hunt rifle was then a Heym SR 20N then also in .243" Win but meanwhile rechambered to 6,5x65 is here to see:

With that rifle i would not have been able to place that Shot. Not because the ,,Beauty" would not well place Bullets in the desired Direction. See a 100 m Target, holed with .243" Win Norma Factory Ammunition with that Heym SR 20N on 100 m below left. No i was not able, because the Green Hills provides no good Rest, i was accustomed to from my ,,Hochsitz" (high Hunt stool) and his Rifle had a Bipod. Peter later in the Dawn then shot a Sika deer across a Valley, through that the Wind blew crosswise. We were slightly sheltered and Wind speed increased in the Open. So i had no Way to to guess the Wind. As it often rains in Scotland (Paradise for there fast growing Sitka Spruce), some Water in the Air helped Peter to read the Wind and place his Shot on 461 or 641 Meters. I do not remember the correct Number, just pulled the Digits off Memory from Mai 2000 now 4 Year later. While a Sika deer is much larger than a young Rabbit ant its shoulder Blade it about 12 x 12 cm, from sheer Geometry a Shot on 400 would have required just about 1 MoA or on the long Guess 0.65 MoA. I tried that Shot, but lost Sight from the slowly moving Animal so often before beeing able to fire, that approaching Darkness commanded an experienced Scottish Hunter like peter Jackson or Hugh Forgie to act, after their Politeness, to offer me Chance would not bring the Desired Prey within reasonable Time before Darkness.

Peter and Hugh discussed Wind and mutually agreed on the appropriate Windage to set on the Scope. Peter placed one Shot across the Valey and the Sika fell on the Spot. Hurray! After a Hike across the Valley, the next Task was to first find and the recover the Animal. Again the two Buddies, well familiar with their Homelands successfully managed that as well. Once we found the Sika, the Animal revealed Reason, it fell so very quick. While the Master aimed for the Shoulder, in Reality the Hit reached the Neck, a central nervous Desaster with consequent immediate Incapacitation followed. Now the successful Shot was a lucky Miss. The 30 cm Wind drift account for 1,6 to 2,2 MoA. depending on the real Distance i cannot recall, but was either 461 or 641 m, as the Laser Range finder read.

Now the Moral of that Story is manifold. First look up on the Heym and find a ballistic Table on the Scope. I learned that from Peter. If you have more than one Rifle or a bad Memory the ballistic Table is always there when you need it and can read it in the Day. Second Peter very lively taught me a Lesson in Wind drift. third i now fully acknowledge his Answer for my question, what would count for long Range Hinting an d Shooting and his Answer was "70 % Success stems from Experience." I thank Peter and Janet for their Invitation an warm Hospitality, Peter and Hugh for their Advice an long Range Shots and good Time we spent and hope to see them on Day in Germany to get them to hunt some Wild Boar.

Less Conclusions for the 30% Rest of the Success, the Story would not be complete. So while the Steward in Command is always most important in the Rifle, the Lessons for the Equipment are rather simple. As Gravity is well known and ballistic Calculations nowadays handle its Influence on the Bullet Path good enough, the remains unknown. We cannot know the Wind on the full Path. So we must use Rifles with Bullets to buck the Wind, to drift at least as possible. To do so the Bullets shall not be retarded and fly fast; a partly contradictory Desire.

I design my Sport Bullets with that very Contradiction, to buck the Wind, to drift less, in Mind. To turn Bullets on a CNC-Lathe offers Advantages, pressed Bullets will never enjoy, slender Shapes, that would let pressed Bullets stick in the Press and sharp Tips, no Full Metal Jacket or Hollow Point Bullet can ever have. With other stuff than Lead in Copper i can stretch the Bullets to even slenderer Shapes, less exceeding weight Limits do not want to pass to keep the Bullets fast. Remember: The combined Speed and low Retardation (= high BC) grant little Winddrift, not high BC alone. Make no Mistake: Choose no Bullet on BC alone. It must speed, not to drift. Full Knowledge grants currently available Ballistic Software. You cannot optimize a Bullet aerodynamically to perform on Long Ranges in the Wind unless you command a full Software suite for interior and exterior Ballistics and a precise Design tool know the BC by Design. This Insight came after many Trials and a lot wasted Money. Once you do it right, Success becomes much faster. Therefore i now am able to design Bullets from Scratch (Sorry CAD-System and Ballistic Programs) with high Prediction accuracy. So far all my designed Bullets flew as expected and, for Hunt bullets, performed in the Target as expected, because terminal Ballistics are the ultimate Goal for a Hit. Why shoot for Paper, when you can shoot for Meat or to defeat an Enemy.

Hello Mr. Moeller:

The .408" bullets look great! I hope you have great success with them. We'll pass your name on to anyone who inquires about the subject.

Best regards, Dave Manson, Montag, 28. Juni 2004 12:58

Dear Sir

We are going to make some of the .408 Chey-Tac Solid bullets without the canular. They should weigh a few grains more than 419gr because of the loss of the canular. If you would like some, we need you to pre pay. You can call Heather at 800-574-9200 to pre order them.

Your .408" Chey tac + 7 mm Tomahawk

Mr. Moeller

I just read your discussion with Warren from Lost River bullets. I tried some of their “great” bullets with no luck. They are magical in that I suspect that one load and one load only will net you the results they achieved but at a price of a small business loan for the price of their bullets.

I had better luck with Sierra and Berger bullets which showed excellent ballistic performance with a few different powders, and seating depths. For that matter the Berger bullets weren’t tolerant of seating depth and gave same performance either touching the lands, fitted into the lands or making a jump to the lands. Lost River bullets never showed signs of any better performance with 7 different powders, and three different seating depths.

I think the mathematical theory is correct and in a computer simulation will result with the type of claims published on their website but in reality they simply do not work as advertised.

I would like to try your 7 mm bullets. I have a Lilja 34 in 1:9 twist 4 groove barrel chambered in a 7 mm Tomahawk, this case is a 7 mm RUM blown out a tad bit and shoulder angle changed. The result is 115.5 grains of water capacity to the top of the neck.

Please let me know the prices for these bullets. I have designed another wildcat cartridge that will utilize a 40 in barrel and a case capacity of roughly 160~165 grains of water. The case has been formed and necked down for the 375, 338 and 308 diameter bullets. I will be very interested once I get the 338 barrel in to try your bullets.

Thank you, Dave Boday, Sonntag, 17. Juli 2005 08:38

Dear Mr. Boday,

thank You for Your Mail. I cannot understand how Lost river Ballistics stays in Business, when so many Folks show up to tell, the LRB Bullets "in reality simply do not work as advertised." I have not sold a lot to America, where I suppose You com from, but read this (I supply the EMail separately, but put them never on the Web, to avoid Spam!):

Hi Lutz,

I thought I would let you know initial results using your bullets in my 9.3 x 62. With 64 grains of Reloader 19, I get 2950 fps and no pressure signs. The powder charge comes up the case neck half way, so I don't think I could fit much more in the case. Accuracy was 3 shots at 100 yards into a 3/8" by 1/2" (inch) group, measured center to center, 2 of the shots touching. This is just amazing accuracy, since my rifle cannot be considered match grade in any sense, and the scope was a 1.5-6 x only.

The alloy has me curious. Although it looks like copper, the specific gravity is too low for pure copper, so I am wondering if it is an aluminium and copper alloy. Don't tell me any trade secrets, but if you can give me any info about the alloy which is not confidential, that may help to satisfy my curiosity.

Thanks again! I will let you know the results that I get on game.

Dan McCarthy, Mittwoch, 6. Juli 2005 18:04

Dear Dan,

thank You for Your Mail.

I am glad, You get along well with the KJG an achieve You Goals. Please keep me updated with Results on Game. Pictures and Stories are always welcome

Quite a few were astonished to get such good Results with the 9,3 mm. I assume the Cause not just in the Bullet well made Precision itself, but also to the Fact, they are lighter than most other 9,3 mm Bullets and therefore shoot more comfortable thereby helping the Shooter, to keep the Rifle on Target. I just returned from Afrika 2005  and have a few more EMails to read and answer.

The KJG - Alloy is 99% Copper  and just 1% different, to allow for better machining. So the Density should almost be that of Copper. If I misinformed the Audience somewhere, I should quickly correct the Type error.

Sincerely Lutz, 16^th July 2005,

The 7 mm KJG work well in 7 mm Rem Mag and 7 mm STW with both 1:9" Twist, or 5,37° Twistangle, considered moderate. So I cannot see an Reason, not to use them in the 7 mm Tomahawk. You should expect:
