175gr SMK batch difference?

[RotARy15]

Bought a box of 100 bullets to build a load, ran out and ordered a box of 500.

Measured the ogive to the base of the bullets with a Hornady comp and the new box of 500 is .010 longer with a variance of about .003 in both the old and new.

Is this typical? Would that change my pressure levels?

Dont worry about it, load them and shoot I doubt you will see any change at all.

sometimes as you hold your caliper the measurments change from the warmth of your hand. But typically I get the same results, a majority of the bullets are pretty close to the same length, weight, and diameter.

175 SMK wieghts range from 174.6-175.7, this is what i have found. But my main groups are at 174.8-175.3. I never really measure and get any outside those.

I am pretty sure that small variance will not change your point of impact. I had the same issue with 178 Hornady AMAX when they went to the AMP production but there was not change of impact so it was no big deal.
