I do not shoot a 45/70 so I am in need of a little information.
I shoot a 43 Mauser. It is a bottle neck case, not much of a bottleneck but still is considered one.
My question concerns BP compression.
All of the data I can find says "never compress an powder in a bottleneck cartridge".
Why?
If I want to get the recommended load of 75 grains of FFG it requires some compression. Is there another way to do it?
Any info you wish to share will be greatly appreciated.
Thank you.
