6mm BR Lapua brass consistency

[bricktop]

Got to measure three boxes of Lapua brass, all from the same lot. Blue box, lot P0033702/2473612. Brand new, not turned, trimmed, or shot. Weighed with a Chargemaster 1500. Here is the data in case it is of interest to anyone...

it sure isn't as consistent as the old gold boxes If memory serves me it was about 1-1/2 gr spread

A few things I do know about Lapua 6mmBR brass is that 1.) it is VERY long lasting; 2.) compared to other brass that is NOT 6mmBR, it RARELY needs annealing; 3.) the primer pockets will keep primers tight even under extreme pressure>>>mostly due to the fact they are SMALL primer pockets>>>>nevertheless, they stay tight. 4.) my rifle ALWAYS stays consistently accurate! For the rest of the inconsistencies, they have never affected my accuracy adversely! I now have a "gold box" (still unused) and I will see what, if any, difference there is any once I break into that box... But until then, I still have ZERO problems with my current brass. That's my 2 cents worth...

Man i don't get the same brass you do. It needs anneal before you fire form, some primer pockets are loose before fired and flash holes are every where now. I don't weigh any more because of the variation on the outside. I anneal every firing to get consistent neck tension...... jim

I wonder how Norma compares? Man, I really do wonder...

I was thinking of doing an experiment where after I trimmed and turned the cases, I reweighed to see the correlation and resulting new distribution.

A few years ago Jason and I combined on six boxes of 6mmBR brass. Jason weight sorted them into four lots. I got two he got two. Now my trimmed and formed Dasher cases are very consistent by weight.

Did you shoot each 1/4th as a batch, or did you sort each lot further for matches and such?
