Ar15 caliber that uses large rifle primers

[SamuelBerryhill308]

Hello all I have a colt hbar match rifle that I would like to build or purchase a upper for that I can use for close range deer hunting and that also uses large rifle primers due to that's all I have on had besides large rifle magnum primers.ive looked at the 6.8sps mostly due to I am familiar with the .277 caliber.but what other calibers use large rifle primers that are suitable for deer size game.thanks

6.8spc Remington brass.

IIRC, the SOCOM is loaded with Large Pistol primers.

6.8spc Remington brass.

That's what I've been looking at.how do you like it?

 

[Carlos88]

A lot. I've been shooting it at hogs for at least 10-12 years primarily using 90-100gr bullets. Speer makes a 90gr Gol Dot and Barnes has an 85gr TSX which are great for shooting them. I'm sure they would poleaxe a deer as well.

You can use 6.5 Grendel brass fireformed from 7.62x39. I did this for a while for the same reason.

Oh and BTW take a serious look at White Oak Armament for your upper. That's what I bought after I got serious about accuracy. GREAT upper.

Another vote for the Grendel. Either form out of 762 or wait to find small primers. It's vastly better than the 6.8

 

[Carlos88]

Not really.

I should mention that when I did this, I used some once-fired 7.62 brass, and for some unexplained reason, half of them had case heads slightly too big for my Grendel bolt. I sorted the brass for this, but some were still snug and made for some feed issues. I was glad to abandon the project when I found small primers.

Another vote for 6.8spc -- I have 3 and love them all-- a short pistol, a 16" lightweight, and a 20" bull

Those 90gr gold dots are great for hunting, 95gr ttsx work well, as do 110 nab bullets--and with a modified magazine to load long and lvr powder I can get 2570fps in my 16" and 2760 fps in the 20" with the 130gr Fusion or 130gr vld's bullets in s&b sp brass (these loads were pressure trace tested to be safe in my gun)
