I came across a posting on another site of a member having issues with some 7mm Nosler blem hunting bullets that were .002" larger than the last batch. I remember a post here a while back of a member complaining that his Sierra Matchking weights "were all over the place". I think it was a couple tenths of a grain?
I personally think the problems with 7mm blems was an anomaly. I have a large amount of Nosler Custom Comp .308 in 168 and 175 grain of different production batches. Checking the 168's and 175's, almost all of them were between .3081" and .3083", that's pretty consistent.
I went on to to a random analysis of the weight variation of 11 168 grain .308
168.0-1
168.1-2
168.2-6
168.3-2
Using my non-scientifically calibrated scale the vast majority, 6 out of 11 were the same. Furthermore, 2 tenths of a grain variation is only .12%, one eighth of one percent of the projectile. I did not measure bearing surface of the projectiles though. Over-all I would rate the Nosler CC blems as highly consistent.
