What purpose will this serve?

NJ,

Unless the weight is off by a couple of grains or more, weight is fairly irrelevant. OGL measurements will lead to better loads and give better info. It's luck of the draw on a box of 500, I've purchased some boxes with a +/- 0.005" OGL and BOL, and a whole lot more with +/- 0.025" variance. Especially with different lots.

HTH,
DocB

It's one way to show how good SMK bullets are. Some like to know these things, and better yet see it.

That's why I used to inspect a LOT of bullets.

To be honest with you out of all of the SMK's i have looked at they seem to be the most consistent.

I have found the lapua scenars ive been using recently to be pretty bad with big variations.

That's odd...

Using labratory grade instruments, I found just the opposite. My results for factory made projectiles were:
Berger, anything
Lapua Scenars
Hornady Amax
Nosler Competition
Sierra Match Kings

While I am not going to post the data I have recorded on all the different bullets I have inspected, I have it saved and filed on hard copy. I tested 3%. That's the same number as DOD and DOE use to inspect off the shelf hardware.

Custom made bullets are in a different category, and ALMOST ALL are better than the factory bullets. But that's what you pay for.

I was shocked too Vic...

Must have been an odd batch or something. I will have to check the current lot i have and see if things have improved.
