[QUOTE="freddiej, post: 2251282, member: 26227"] Since I have not seen this put out, here is what I am pretty sure is part of the answer. new barrels are rougher unless they are hand lapped from the factory. if you have 100 FPS faster and take a bit more powder to give the same pressure and velocity then your barrel has burnished in and is slicker than it came from the factory. I learned this from my own experience. once my barrels were bunished (shot in) they had lower pressure, lower velocities, and took a bit more powder to bring them back to what I was used to. this could be part or most of your answer.
