I have several 300RUMs of which I handload for. Certain guns I use Rem brass, and others I use Nosler. I've been very careful to keep all brass separated for each gun, along with how many times each has been fired. All of my guns have the 700 Rem action. Long range accuracy in all hunting conditions is my main goal with all the rifles. Does anybody think I'm going too far keeping the brass separated for each gun, beings they are all the Mdl. 700? It would be so much easier to just lump them into containers pertaining to how many times they have been fired. Thoughts? Thanks.

I think what you are doing makes sense. The best accuracy is by using brass shot out of that particular rifle chamber and when you reload, just bump the shoulder a little bit and don't full length resize.
-
Curly is spot on. With factory rifles where the chamber may not be consistent, then keeping the brass separate and just bumping the shoulder will give the best accuracy. All of our personal rifles have been setup with the same reamer and same headspacing, so we can interchange brass. Factory headspacing sometimes is marginal, so for maximum accuracy, your best to keep things separate.
Just a suggestion, if you ever have a multiple rifles built in the same caliber, or you and a buddy have them built, have the smith setup the chambers with the same headspacing. This will allow you both to use the same brass.

I disagree... You can only neck size but for an ultra mag, to get the life out of your brass, I would definitely full length resize every time. You can definitely use fire formed brass but for hot loads with 80+ grains of powder, I would full length resize each time as those cases get a LOT of pressures compared to other non mag loads.
I personally do not use the brass more than about 7-8 times and inspect it pretty tough.
Keep it seperate though, definitely! with relaoding its all about subtle differences and those differences are pretty key! Personally I think Rem brass is junk and my rifle does not like it as much as other brass.
Nosler and Federal Brass is what I use. :twocents:

I always keep my brass separate for each rifle.

MDG, how will you get more life out of the brass by FL resizing? :dunno:
-
Generally bumping the shoulder will also FL size. The neck sizing dies I have only size the neck and never touch the shoulder.

I guess this is what I'm getting at by mixing the brass. Two of mine and one of a buddies have the same headspacing.........but then people say definately keep them separate. By no means do I know a lot about this, just trying to hopefully simplify my RUMs.
Thanks for everybodys input. :)

I have bought used brass and resized and got the same accuracy as brass shot in my rifle.If you fl resize it goes back to ground zero and should fit standard chambers.you could resize a case from each gun and and fire a group out of one gun and see how the mixed lot groups.
-
I've read that Neck Sizing dies are made to resize brass that has been fired in a large chamber, just enough to bring it back to reasonable "spec.".
Don't really know. I neck size .204 Ruger and .17 Fireball brass, because I only have one rifle for each of them. For my 3 .223 ARs, and the 6.8 AR, I full length resize.
-
Neck sizing just resizes the neck to hold the bullet. I like to bump the shoulder on loads I hunt with to get dead slick feeding. I have had up to 4 rums at once and the chambers are not the same...close, but to neck size would keep from chambering in some of them if lots were mixed. I have had good life from REM brass, but I reccomend measuring after a couple loads. The accuracy lost by fl sizing is worth the slick feeding to me, I can give up .02 moa for it.
-
For hunting i only like to use once fired brass,after reloading i cycle each round if any are the least bit hard they get saved for sightin-plinking,over 40yrs i have experienced the the problems that will come up if you reload.
-
Every rifle is different. If you want to make sure that all the factors influencing accuracy are acounted for, I would keep the brass separate.
Gadwall.

Keep in mind that time is critical in a field shot. If you load up ammo to win matches you may not be able to feed it quickly or from the magazine. For my field guns, smooth as glass feeding is worth a small loss in accuracy. When a bull is walking over a ridge would you rather have a .9 moa gun you can row a shell in every time, or a .5 moa gun that takes a full second to fiddle with. Chances are you can't make up .4 moa on a rushed shot.
For the bench......pull out all stops and rock on
