Why you separate brass.

Didn't think any of you guys would be interested in the old once-fired brass......

Hey it's not that....really B), we're just trying to help you out by taking it off your hands <lmao> .

Too late... they're all gone. All 15,000 lbs of it.

Who snatched 15,000 pounds of brass?  That WOULD make a pretty nice paycheck at a recycling place in the city...  Can't really blame someone...

"some reloading company" was what I was told. At $3/lb, the recycling place would have received $45k...

Yep, brass can be a real stickler for downrange consisten hits, like 98Z5V said.  I've loaded Hornady new Match grade brass and found a nice load, and once it's fired, oftentimes all bets are off on the resized brass and same powder/primer combination.  Different manufactures of brass are very close to each other, but often different in some very minute way to make what happens in a millisecond count.  I'f shot SSA brass in the 6.8 and the loads that were accurate for it were not accurate when I moved to other mfg cases.

    If you look at Velocities  ( if you use a Chronograph for testing ) you can see in grouping at a certain range , that there could be multiple velocities that print good groups , at that particular range ( sweet spots ). So if you get brass that has a different case volume ( velocity could change ) , with your loading , it could be out or of the sweet spots for groups .

   You just have to make notes & adjustments for that brass , it usually changes with brass brand , but different year head stamps of mil spec ammo could also change. The fact that you are fire forming the brass in that particular chamber is another good reason to sort & use the same brass for that chamber , even though you resize it (FL or SB ) SB being closer to SAMMI spec's .

These are some variances separating about casings of hornady brass.

  You could be picky & use 0.5 as a variance , but i would put 2,3,4& 5 together & keep # 1 separate . You can also play with # 1 to match close to the same results as the others , being the Velocity will be a tad lower . Might not even make a difference , only testing will tell .
