I recently had cause to remove the paper patched bullets from about 30 cartridges.
These were loded 2 weeks ago,and most of them left pieces of the patch in the case mouth,when I pulled the bullet.
I wonder if this occurs when the bullet is fired form the cartridge.
I suspect that,upon fireing,the neck is expanded,negating this problem.
Does anyone here,know the truth,or have an opinion?
