I started a thread over on 6BR area, as "Dasher 87VMAX" issue. But it has little to do with the Dasher and everything to do with the fact this bullet is measuring .2434 - .2435 throughout the entire body/bearing surface, which is 1/2 thousandths larger than any other bullet I measured. I believe that's the diameter of the freebore/throat area on most match chambers, so there is a serious fit issue here. I was testing these bullets a couple days ago, with first 5-shot group giving me 1.5" at 500 yards...then groups started to get hard to chamber and groups opened up, following by complete inability to chamber a round. Got home, and FB measured zero (really, much less than my zero freebore 6BR), yet I have .105 FB.
I'm wondering if all lots of 87 Vmax measure this large over the bearing surface,,, I'm betting so. In which case, this might explain why such a high percentage of shooters with 1-8 twist Match rifles (6BR, 6BRA, Dasher, etc) aren't able to get these bullets to shoot well...the clearances are so tight that they are probably getting pressure spikes.
