[QUOTE="SpikeSniper, post: 1098160, member: 29703"] Bountyhunter, Let me elaborate. I typically sort bullets based on base to Ogive length, which was all within .0005 in this box and in the original. Most boxes of bullets I have found to vary 0.1-0.3 grains, SMK's typically can be divided into 2 lots of almost equal weights, IME. I did weigh sort these bullets with no noticeable difference in accuracy. It was not until I started trying to fix the problem that I thought to use a separate .284 caliper insert over the boat tail to measure bearing surface. That's when I found the .005" difference. I think I mis-typed that in my original post. But I even sorted down to 3 bullets that were virtually identical by any means I could muster to scrutinize. They still shot a 1.5 MOA group with the same load that was shooting 0.2. While the original 100 I used to develop my load shot outstanding without sorting. I don't know if they varied that much or not, because I didn't check them beyond base-Ogive length. What I know is that the Nosler rep brushed the deviation off as "within specs", while Sierra, Hornady, and Berger bullets do not show that much difference from the ones I have measured. [/QUOTE]
