This is a very bad day to see this question asked. With my favorite .308 load they actually group better than most of the other primers but at a price.
I was in a Hunter BR match today (factory calss) and out of the 50 rounds I had loaded for the match 14 of them failed to fire.
At the start of the last relay I had 8 rounds left and only 4 worked. With 1 minute remaining I was out of ammo and still had one target that needed to be shot. I ran down the line and grabbed two rounds from a friend, I fired the first shot at the sighter and made a quick adjustment and in the last seconds I shot the last target for an 8. It ended well because I won the match but If I would have dropped that 10 points it would have been over for sure.
I went home and tried more Rem primers out of another NEW case and 1 out of 5 failed to fire. I tried another gun and had the same results (3 out of 10 failed). Bolt protrusion was .35 on one rifle and .46 on the other and both were hitting the primer hard.
As for storage, they were picked up in person from Grafs reloading, brought directly home and stay a constant dry 73 degrees in my house with 8000 other primers that dont misfire so I don't know what their problem is.
Its one thing to have problems in a match or playing around but if I waited all year or went out of state looking for the Buck of a lifetime and he got away because my gun wouldnt fire I would still be cursing about it.
I would say its hit and miss because I have had other cases in the past that I dont recall any failures, However I cant afford to take a chance on them anymore because I spend to much time and money in shooting sports to have a $3 package of primers ruin my day.
