Fast twist barrels

[45bpcr]

Hello all,

Are there any thoughts on fast twist barrels and bullet over stabilization at cast lead bullet - black powder velocities?

The reason I ask is my wife's 38-55 C-Sharps wears a 1-12 twist 28" Green Mountain barrel. She does pretty good on her lay down animals shooting a 365 grain BACO Creedmoor powered by 41 grains of Swiss 1 1/2F.

Chickens are another story. (Aren't they all )

I have a Lyman 2 cavity 375248 that I use for my 375 Winchester 94 and was thinking of using it to make a High Speed / Low Recoil chicken load. These bullets are .945 long as opposed to 1.41 for the Creedmoor.

Thanks,

Craig
