I’ve ran a full box, now on box 2 w zero issues

I lined up on a big pig and got the dreaded “click”

It’s shot well actually 1” groups

Is this stuff known for hard primers?

I had a .308 Power Point do the same thing at the range. MiGht be a thing with their ammo. I think most of the mainstream ammo producers like Remington, Winchester, and Federal have gone way down hill since I was a young man.

The only primers that I know of that people consider hard primers is some of the CCI line. That looks like a firing pin issue. I had a super Redhawk that would not ignite cci small magnum but would Winchester.

Good luck, and as always, I could be wrong.

Failure to fire I have seen on all primers.

The picture you are showing is not an ammo issue. The dent on the primer is not near enough to go off. Something with the rifle caused it not to go off. The slight mark you can even get from chambering a round in an AR. That's not an ammo issue.

Did you have the safety off? Yup, normal AR cycling dent.

I’d pop the case into a case length headspace gauge and see if it tells you anything.

I agree with the above. The problem is in the rifle, not the ammo. That little mark didn't get the full weight of the firing pin on that strike for whatever reason.

I had the same issue just a few weeks ago on a reloaded 708. Shot a pig that was walking, it ran off. Knew when I found digested acorns in the blood what happened. Tracked it, and found it alive. Aimed to dispatch it, CLICK!. First time in over 30yrs of reloading to hear that sound from my ammo. Cycled in a new round, boom. Picked the suspect cartridge up and primer strike looked about like yours. Chambered it back into the rifle, pointed it at the ground and it went boom. Still need to disassemble the bolt and see what has the firing pin obstructed.

It may have been a light strike, it came from a brand new just out of the box Ruger Ranch 300 BO, round count of 22-23 max

Still breaking it in. I would still take the bolt apart and clean it.

^^^this. If that is from a bolt gun, then it obviously is not a normal dimple from chambering a round. It is definitely a light primer strike. First thing I would do is disassemble the bolt and clean it. Could be a small piece of metal shaving form manufacturing stuck inside the bolt, or a piece of dirt. Could be a headspace issue, but I doubt it. Clean the bolt, then put that same round back in and pull the trigger (with the gun pointed downrange). I'll bet it fires.

Mine did the same thing with factory Barnes loads with crimped primers.After 3Times Ruger, they said it was from Military brass and the primer being seated deeper in the case, especially with staked or crimped primer pockets. All I know if I started loading my own and had Zero issues. Initially I was pretty pissed. Now I just know what it will won’t shoot. At the time mine was brand new at $300. I’ve got almost 2,500rds down my tube and it’s still a Great shooter, with commercial brass and a WSRP. In a Barnes 110Tac Tx factory ammo box I’d have 20% not fire just like above.
