Besides the .001" difference in diameter, what's the difference, pros/cons to using one size or the other in a .45 ACP? Berry bullets are .452" and every other projectile and commercially available round for the .45 is .451." I read Berry is widely used in IDPA, but cannot find any other manufacturer that makes/sells .452" bullets for use in a .45 ACP (only for .45 Colt).
I ask as I had a bad experience with an over-sized reloaded projectile. Thanks!
