Final report on that lousy .308 ammo

Well, excuse me, 7.62x51mm ammo.

I pulled five more. These powder charges varied from 42.0 grains to 43.9, in five rounds from the same bag of ten. I thought I'd post the entire 15 here.

First five, all in grains:
40.8
41
42.3
42.5
42.6

Second five:
42.4
42.3
42.6
41.0
42.2

Last five:
43.9
42.0
42.6
42.4
42.7

All were ball powder; three of them had some kind of waxy-looking crud stuck on the base of the bullet. So that's a max variation of 3.1 grains within fifteen rounds out of two ten-round bags from the same can, all with identical headstamps.

I weighed twelve of the bullets, three having rolled out of reach for the time being. They weighed from a low of 145.9 grains to 149.2.

Keith asked an interesting question, so I weighed the ten cases that were immediately in reach:
188.1
190.3
191.5
188.1
188.6
187.3
189.4
189.4
188.5
193.4
So a max variation in primed cases of 5.3 grains. I've never weighed cases before, so I'm not sure how that fits in as far as acceptable variation.

So be at ease, Kevin, the rest of this will not be fired by anybody. And I'm damn glad a: it was cheap and b: I only got 100 rounds.
