I was getting ready to purchase some 230gr bullets to reload for my S&W M&P 45acp. I noticed that some of the vendors sell 230gr's that are .451 diameter and others have .452 diameter. Short of slugging the barrel, how do I know which size is best for my gun.
I am planning to get FMJ not lead bullets
