Ok, I know I should not be in any sort of hurry with a new rifle but, I am sort of. Its a long story but, the rifle got done late and I am leaving tomorrow once I get the barrel break in done. Worse case scenario I can shoot some factory rounds but, I would rather not do that. Ok, here is the gun and the issue. Rem 700 257 WBY. I had Shawn take the freebore out. Not sure exactly how much he cut it down but, he cut it down to what he felt was best. And yes I tried calling him, all day! I am sure he is hunting or something. Anyhow I was trying to determine COL for this chamber. I was trying to take a short cut. I took a fired case from this chamber. Dented the mouth and shoved a 110gr Accubond in it. Used a marker to color the bullet and chambered the round then tapped the bullet out of the lands. You can see how far the bullet went into the case by how much of the marker was scraped off. The problem is that if this is truly my COL, then it is really SHORT!! The books say 3.250 max COL. This cartridge was 3.154". If I wanted to be .010 or .015 off the lands then it would be somehwere in the 3.139-3.144 range. Factory loads are around 3.155. What gives? How is this going to affect my loads? Do I really want to chamber the round this short? I did up a dummy round at 3.250 and it chambers fine. What am I missing??? HELP ME BEFORE I GO CRAZY!!!!!!!!
