Match brass ?

[CZ550]

Ok I have a 100 pieces for my 6.5x47 how many pieces should I set aside for match brass? I have been just running all 100 thru and starting over, they will be on there 3 firing.

Is it important to keep all the brass with same amount of firings on them?

What do you guys do with a box a brass when you plan to compete with it, do you dedicate 50 or so for match use?

Yes it is important to keep your brass separated by the number of firings on them. That way they all behave in a similar manner while shooting. The neck tension is one of the keys to accurate ammo. After brass has been used for a bit, it tends to loose some of its spring back. To cure this you may want to look into annealing your cases.

I like you keep 100 and run through them. Picking up where I left off from last match. I number them with a scribe toll to be sure they don't get mixed up. Makes their performance easier to track also.

I don't distinguish between match brass and practice brass, because I firmly believe you should practice as if competing.

As such, I rotate through all my brass in an orderly fashion. Some shooters I know do that with about 15 pieces until they've fired them in competition a few times and then simply throw them away [I'm referring to Lapua when I say that].

I'm a little more conservative and less wealthy, so my 100 pieces of brass gets rotated through until I start to see some hardening when sizing. At that point, annealing has been known to extend its life.

With a fresh barrel I start out with 100 new cases for Match brass. When that barrel is replaced those 100 cases become my practice brass. The new barrel gets a new fresh 100 cases for match brass. The next barrel I toss the first hundred and just keep rotating that way. Works for me.

I use my OLD barrel for fire forming new brass. Since I own my own reamers and use them on the new barrels, the chambers are identical. That way I don't over-wear a new barrel just for fire forming, and the rifling stays nice and sharp for matches.

With four shooters in my family, I"ve had plenty of opportunity to experiment with mixed brass. Even after annealing, I find there are indeed differences in neck tension. I'm pretty confident that you want to segregate your brass and keep it that way even if you anneal.
