mixing brass

[porthos]

i have 3 6.5x55 swedes ; 2of them have their own lots of brass. the other is a CG-63 that i just bought on gunbroker (hope to get it next week) anyway i have several different manufacturers of other brass that i would like to use for it. for example 2 different norma headstamps, 1 ppu and 1 pmc. without keeping them seperate; could i mix them without any effect on accuracy. this is,if i fl size, trim, anneal and if the different brands weight within a couple grains

There will probably be a little difference, but usually not much.

If you want to tweak out the last little bit of accuracy, and eliminate one more variable, keep 'em separate.

You could mix them if you full length resize
But, what is your accuracy requirement?
This will require testing with your rifle.
Shoot one group with mixed brass, and another will
sorted brass, you will soon get the picture in what
works with this particular rifle

I shoot mixed brass in my handguns and in my AR and H&K. I have a favorite load that I use and load these batches up by the thousand. The loads are never max loads and they are surprisingly accurate.

But I use matching headstamp brass for my hunting, defense and competition ammo. Or for max or near max loads.
