[QUOTE="Barrelnut, post: 903917, member: 74902"] Bearing surface is the part of the bullet that actually contacts the rifling as the bullet moves down the barrel. Theory is that a longer bearing surface will cause the bullet to have less velocity as it has more physical resistance while traveling down the barrel. Don't even think it is theory really, as you will notice in reloading manuals you can see the velocities change between differently designed bullets with different size bearing surfaces, even though they are the same weight. You will enjoy ready the articles in the link below. In part one case prep is discussed. At the end of part one is a link to part 2. That is where sorting bullets by bearing surface is discussed and really gets interesting.
