Re: 45 acp bullets in a 45 colt?
Swagged the barrel and mic it see what it comes out as..
some times its tighter then you think some times its more ""loose"" use a .458 round ball or a .454 size if you can get one... use dowl rod slowly tap it down then measure lands/groves.
reason you can go little bigger is again they are made little loose especially lower quality firearms and it basicley swagged the bullet down the barrel with a little more preasure build up.
