I bought some bulk 230 FMJ (not plated) bullets for my .45 ACP the other day. I just noticed that they are .452 diameter instead of .451. I have used 4.8 grains of Titegroup with the .451 230 gr FMJs for a while. Do I need to adjust my charge weight at all due to the diameter difference or do you think that this is a negligible change? The weight is the same, it's just the diameter that is different.
For what it is worth, I am shooting a classic Sig P220.
Thanks.
