308 brass? please help

[50bmg1979]

Can someone tell me what these cases are. It says small primer 308 but the remington BR is throwing me off. I got a couple hundred for a good price and was wondering if they would be ok for my 308 AR

If I recall they are old cases, lapua wasn't the first to make the 308win with a small rifle primer. So that's all they are 308win that use a SR primer rather than large.

Were these not the early brass Rem put out to form the 6 and 7 BR? It had small primer pockets. Was it not annealed for forming also? You might want to ask this question on benchrest.com forum. Those guys will remember.

Ok thanks.

I'm pretty sure my dad used that same kind of brass to form his 22 Cheetah mark 2. cool find.

Remington URBR 308 Small Rifle Primer brass was produced to make 22,6mm,7mm BR brass before Remington manufactured brass or ammo.

First production run URBR brass had .062" flash holes & 308/7.62x51 NATO shooters had ignition issues when temps dropped into the 40degF temperatures.
Late production run URBR brass had .075" flash holes & ignition problems ceased.

Remington 6mmBR reloading brass to date is manufactured with out a flash hole.

I use Rem URBR brass exclusively to form/shoot 22-250,6XC,243,6.5-08,260,7mm-08,308,7.62x51.

308 BR use small rifle primers for a time years ago Remington made a batch.
Now Lapua Has copied it.......Some shooters mostly Palma shooters claim more consistent ES using the small rifle primer mostly the 7.5 BR primer. The milder the spark the better the ES......Hence the RWS and Rem primer. for hunting loads I like a normal primer like Fed 210 M or CCI br2 primers. Yes they should be OK.......but I suggest a CCI br4 primer since CCI kinda have a harder cup for the AR. The newer Fed AR primer should also work great.

So should I sale or trade this for different brass? I wouldn't want to ruin this brass by shooting it in a gas gun if someone could use it. Thanks for the help.

It was meant to be shot so shoot some with the small primer and see how it goes.

It is special brass,you can probably get up to $20 a box selling it to someone who will form it into a wildcat. Use LC brass in your gas gun.

Ditto...it will make some wildcatter happy. You can get brass for a gas gun easy enough...harder to find brass to make into BR or other.

Thanks guys. I put it up and it didnt last an hour. Thanks for your help. I would rather someone have it that would use it for its intended purpose.

It is junk. Send it to me!



Back in the day, that was one of Remington's "Bench Rest" products. They had 308BR's, 6BRs, and 7BR's. All had small primer pockets and were supposed to be made to stricter tolerances. At the time, it was pretty good brass. Today, there are quite a few that are better. Still a collectable tho....especially in the original box.

"collectable" yeah, I use the stuff to collect 10's and X's at 600 and 1000 yards. Sorry, but the boxes go in the trash. The stuff works great, David Tubb used it for many of his championships back in the day. I have a batch on it's 8th reload with a 46gr of 4064 and 155 palma bullet. For a gas gun there is tougher brass and that is better for that application, but in a Palma rifle the stuff works great and is cheaper than Lapua or Norma and is plenty tough. If the small primer could help me read wind better then it would actually have an affect on my score!
As far as case wall consistency, I have measured Win, Lapua LR primer, Lapua SR primer, LC match from the 60's, and URBR. Remington URBR makes everything look like LC ball brass, nothing is even close in wall consistency. Maybe Norma is better, I don't know but Lapua is not even close to URBR.

Probably the same cases used when Jim Carmichael developed the 22 CHeetah. They were small primer pocket cases necked down to .22. Obviously Lapua didn't make brass back in the early 1980s.
