It is a .308

Running steel case ammo through a bolt gun? Wouldn't recommend it.
There have been quite a few in at the Range that were having the same issue.I think it is a firing pin problem.No matter the primer it should always set it off.pin to short or spring to weak one or the other in my opinion.Look at the pin mark very weak not deep enough indention to break the primer is what i have seen.

Some ammunition use harder primers for semi automatic rifles.I agree with Sharkbait, hard primers. I've been using Rio shot shells for over a year without a problem until a 5 day shoot in Vegas, broke two firing pins on my Browning O/U. The Browning Rep was in attendance so I asked him what was my problem with the pins? The first thing he asked what ammo was I using and I told him Rio and his response was Rio had hard primers that will damage pins and only cause a slight dimple on the primer. Now after 10K rounds if Federal or Winchester not a hiccup.
I've never even heard of Tula. You can buy Winchester power points for less than $20/box.
Got an update from the buyer, he switched ammo to a box of Winchester and the rifle shot flawless.

Ok, so maybe something to clear the air here. I am pretty sure the COMBLOC ammunition is meant for semi auto rifles or at least they are covering thier bases.The harder primers are sometimes needed in semi auto weapons. Many semi auto rifles use a floating firing pin and there is a chance, however slight that firing pin inertia could ignite the primer. There are also concerns with crew served weapons that fire from an open bolt. I use BR-2 primers in my M1a. They are known as a soft primer, but I've never had one slam fire. I've cleared that rifle and had the chambered but unfired round show a light primer strike. I would never use this ammunition in my FAL, Ar10 or some AKM based rifles.As far as shooting .556/7.62 in bolt rifles chambered in .223/.308? I've done it for decades and never had a single problem. Last... As long as I'm at it. You only need small base sizing dies if you suspect that the brass has been fired in a belt fed open bolt weapon such as a FN 249 or 240. The chambers and headspace can vary widely and can deform the brass making small base dies necessary. NOTE... Do NOT fire commercial ammunition in a wiped out beltfed machine gun. *********Google was not used or abused in this post*****
