[QUOTE="c_bass16, post: 1047583, member: 20355"] You're not going to lap it any better than the bullets have already done. .25" of erosion isn't life threatening. my .243WSSM had about 6" of fire cracks and 1" of erosion and still shot .75 MOA. A lot of times, with erosion, you need to "chase" the lands by seating your bullets farther out so that essentially, they are back to a consistent jump distence. Of course, your powder charge would need to be tweaked as well, since seating the bullet out will reduce the internal pressure. [/QUOTE]
