.308 brass

[Gundogblue]

I hope I’m posting this in the right section. I’ve been shooting and loading for a Savage 10 FP .308 bolt gun. I’m getting a new AR10 in .308, can I use the same brass I’ve been loading for my bolt gun in the AR10 if it’s full length resized?
Thanks ,
Paul

Absolutely. The chambers will be very similar, and the sizing die reduces the brass to basic size.

Depending on the chamber of the .308 AR10, you may need to full length size brass fired in any other rifle to get it to chamber without issues in the AR10.

[Winger Ed.]

No problem. If anything, the AR chamber might be a little more 'generous' than the Savage.
Worst case scenario, you might need a small base sizing die for the AR.
I'd try the regular FL sizer first before I bought a small base.

Years back, I had a real tight chambered heavy barrel Winchester model 70.
I sort of neck sized for it. I used a FL die, but didn't set it down all the way.
I also had a rack grade M1A and was careful to keep the FL sized ammo for two separate.

Just 'to see what happens', I took neck sized ammo for the Winchester, and tried it in the M1A.
It ran just fine in the slightly more 'generous' GI barrel.
I still loaded for them like I always had, but didn't really have to if I made all my cases to fit the Winchester.

You may or may not have similar results with your two .308s.

GONRA sez its best to always FULL LENGTH RESIZE for all semiautos
to ensure Free Chamberiig / avoid SLAM FIRES! !!

Thanks much for the info, I greatly appreciate it! I always full length size my cases, in-fact I have 100 rnds already loaded up for my Savage bolt gun. They’re 42.5 grns of RL-15 behind a 168 grn Sierra Match King boolit. They work great in my bolt gun, that don’t mean they’ll work great for the new AR-10, but that’s where I was gonna start, so now I don’t have to get new brass and load up a bunch of rnds, this makes it fast and easy to try out the new AR-10.
Thanks Much,
Paul

Let me suggest that you get a main reloading manual (Sierra, Lyman, etc.) and READ it. If you had you probably would not have had to ask this question. Reloading is about a lot more than finding a load for your cartridge.

[GONRA]

Wayne Smith - GONRA remembers noting years ago - reloading manuals were pointed toward the bolt action guys.
Admit that's probably changed today? Every home hasan AR-15.......

Save yourself a lot of grief !
Buy a brand new lot of Starline cases for your new AR-10 .
Keep the brass for the bolt action ... for the bolt action .
Depending on how much shooting you do with the AR-15 , get enough brand new cases to cover your needs twice . Brass will wear out and having more from the same manufacturer lot ... will make your reloading much more better .
Do NOT start with mixed oncefired range brass ... it will cause you pain .
Get 500 new Starline cases , same lot no. ,
and be happy-happy !

And keep the brass for each rifle seperate ...
Things work better that way .

Yes to all of the above. I’d suggest segregating brass for each rifle as it will last longer and give better results. Not sure how many you need to feel comfortable but 308 brass is everywhere. Good luck. You will then start itching for everything out there based on that great case. Buckle up.

[Shiloh]

Sure can. Full lencth size the brass.

I FL size all my ammo for my DPMS .308, Savage 110 BAT/s, and Springfield M1A. I don't have storage space to store or time to custom make ammo for all three.

[Rapier]

An alternative to separate fired bras storage is marking your brass after preparation, on the base with a small ball cutter head and a motor tool. I just use a line, two lines and an x for three different guns with the same chambering, the marks do not come off or mar. Allows you to clean all together then sort in the loading block, neck down for sizing and priming. can use various marks for match brass if you shoot competition. Tried all kinds of sorting and marking, nothing lasted like the cartridge base cutter lines.
I also full length resize all of my semi auto brass, irregardless of type, either for handgun or rifle.

I have several .308 Savage 99's and several Savage 99's in 300 Savage I shoot regularly. I keep the brass separate for each of them. I use the Redding Competition Shellholders to maintain the slightly different resizing lengths for each rifle. I use the Redding 'S' full length and neck-size resizing die on the 308's depending on load and expected usage, again keeping brass separated by lots, keeping record of times fired, what load used. I have multiple rifles in the same calibers that are duplicates in calibers, but do try to keep brass separate for each rifle.
