Hi Lutz
The .375" H&H developed a sticky bolt and the case was difficult to extract at
4.8gm MV 1027m/s. so I'll knock back the RL 10x and work a load between 4.6 and
4.77gm. Next load development is based on consistency.

Hi Lutz
Lots of discussion on our web forum about the stability of the .375" bullet.
With a 1 turn in 12 inch twist, I calculate that the bullet is very stable.
Others think it is unstable and will keyhole. What's the answer?

LM: Mark, do not let the nice Numbers above fool You. Multi digits mean in this Case only computerized Guess work, not more. But 3,08 s1000 ms is grossly above the required Minimum, so be assured, they will not tumble! Also the 9,5 mm KJG is quite similar to the 9,3 mm KJG and that flies nicely from 9,3x62 and 9,3x64
You should get some nice groupings from me next week when I get to the 100 m range.
9,3x62 KJG Loads + 9,5 mm Recoil brake (recommended for for .375") + Tin boar
Boar hunting was unsuccessful last night but we did see one Keiler 100kg but by the time we spotted him he ran
away.

Dear Mark,
thanks for the Pictures. When You claim 16 mm for 4 Shots "super accurate", I wonder, what You shot before!

Hi Lutz
Many thanks for the 308 bullets. I cant get hold of any T2000 in the near future
so if I substitute 10X as it works a dream in the .375". I shot
Another Scottish Roebuck
on Monday with the 7x64 as he was running away ay 128 m. He ran another 25 m after
the shot. I stalked him down twice over 3 hours as he was being chased by an old
buck over territory.
