View Full Version : LC Match Brass w/ Cannelure

December 24, 2006, 13:43
Mixed in with some LC Brass I bought are a few LC Match that have a cannelure around the base.

Will this affect their reloadability?

In my experience, it reloads the same. I've never had any issues with it, but I'm sure you'll hear a rumor about this stuff sooner than later. Some folks believe it lends itself to case failure because it creates a weak spot in the brass.

If you're uncomfortable with it (I'm not) in a semi-auto, trade it for normal stuff. Or, use it in a bolt gun. Or, just give it to me... ;)

Hope this helps.

I have some of that brass too. In my experience I've never had problems with it. I used to shoot service rifle competition and the guys that shot M1A's all used that brass without problems. I wish I had more of it.

IIRC it was LC stuff that they loaded w/the 168gr Sierra HPBT.

Yep, known as M852 Match. Made from 1982 until sometime in the early '90's. The cannelure indicates that it was not permissable to use this ammo in combat. This was prior to the U.S. determining that Sierra's hollowpoint bullets were not DESIGNED to expand, and our subsequent adoption of the M118 LR ammo (with it's 175SMK bullet) as our current sniper ammo.

I asked the same question on here a few years ago. I have loaded quite a bunch of this brass since without problems.

Thanks, M852 had escaped me.

M118 = 173gr projectile
M118LR = 175gr Sierra (my new 1,000yd projectile for 7.62)

(read his response next to the pic of him holding the .50)

I'd always been told that the 173gr stuff was superior to the 168gr at 1,000 yards, but it seems that may not be the case.

Regardless, I personally think that the idea that the case is more likely to have a case head separation due to the knurling is just speculation. Shoot away, or I'm sure you could trade it very easily. I don't believe it had a crimped primer pocket since it's match ammo, but I could be wrong.

No, it doesn't have a crimped primer pocket.:)

The first year XM852 came out, the canulure was too far back on the case. There was some fear that there would be case head separations. The following year...and all other years it was made, the canulure was moved forward on the brass about 1/4 inch or less.

I've never had problems reloading the stuff...but my guns all have tight chambers.

You WILL hear the urban legend/myth that this brass will separate after the first reload from the all-knowing 'mall-ninja' types who have probably never even reloaded any. They read it on the Internet, so it MUST be true.

If it was subject to head separations, I doubt seriously if Uncle would have fielded it in the first place. I've worn out all that I had; wish I had a bunch more!
