hi guys well today I bought some H4895 (AR2206H) here in OZ. I want to make light loads for target shooting in a WIN 94 .30-30 with a 165grn RNFP bullet.
The bullets are cast with a BHN of 16, Hodgdon list 17.5grns as a minimum but the Lee manual goes down to 15grns, which would be below 50% fill, is H4895 safe at that low level?
Has anyone used H4895 at 50% or below fill? Does it need fillers for such small loads?
I like the look of between 18 and 20grn! At the top end Hosgdon list 21grn where as Lee list 29grn, though with a BHN of 16 I think a load over 23grn would cause a lot of leading.
Anyway to the point, if a BHN 16 bullet can take ~ 24000 of pressure, to what extent would a gas check allow me to raise pressure and velocity for heavy loads for hunting? e.g. 1800-2000fps without using another projectile?
