WOW. You can likely have a reamer and dies made from it. It would be better if it was unfired at then it could be copied exactly. I wonder how much it is expanded over a unfired round
250 grain bullet that is a hunk of metal. the mag is a total score. how does it differ from a 7.62 mag?
it appears that the case taper is straighter than a 7.62 round is this correct? or is it the same?
