[QUOTE="royinidaho, post: 267264, member: 2011"] AJ I'm sorting Berger 7mm 168s and 180s (source of that 12 gr number) after I squeeze them down to 277. The bullets are pretty much +/- Zero for weight but vary a bit in overall length. Bearing surface varies a bit also. I know that vertical stringing @ LR will appear due to varying bearing surface length. What I was wondering is what's the odds of approaching the same velocity with both bullets with the 12gr heavier bullet's bearing surface being about 0.013 shorter? I guess I'll find out when I start shooting.... [/QUOTE]
