All military ball ammo is loaded with these type primers.

Commercially, only Remington 7 1/2 and the special order CCI are MilSpec. These two should be used for handloading if you're loading for a military semi-auto.

Wolf makes a primer specifically for loading 556 ammo for AR's. It shows no dempling in any of my AR's

I have not tried Wolf primers but CCI military primers do show a dimple. My next order of primers will be Wolf though as I hear they are effective and cheap.

CCI makes "mil spec" primers also.

Several years ago I took mine into the local gunsmith/store and they said its normal.

Thanks for the update. I wasn't aware of the Wolf being MilSpec. it makes sense though, since Wolf is primarily a military facility.

I've been using Remington primers exclusively for almost 30 years now. Never had a problem, so I just stuck with them.
