Had touble last year with getting my rifle to shoot with a new box of Hornady 7mm 139 gr. SST. After measuring the base to ogive found a .010 difference between the bullets. Order three boxes of Nosler 7mm 140 gr. B-tips and found less than .003 between all three boxes. Pick up 2 boxes of the SST and first box had 2 differ lengths. One at 1.614 + or - .001 and 1.618 + or - .001. About 1/3 where at the shorter length. 2nd box measure at 1.614 + .001 and - .002. Boxes were of same lot number, Nosler was 2 boxes same lot number and 1 was different. I think this shows that Nosler is doing a great job at QC. Not sure how much this will help shoot better, but thought I would pass it on.
