Actually I even found a post from one of my own members that had problems with his LHR and primers:

"Went to the range to sight in the Redemption. I'm using BH 209 powder and I mistakenly grabbed the CCI muzzleloader primers instead of the CCI magnum shot shell primers. Only had one partial ignition short round which surprised me out of about 15 shots. About half the primers were very hard to remove and a few needed a tool because I couldn't remove them with my fingers. I'm hoping the CCI magnum shot shell primers will be different.

Unlike NAME REMOVED, I did experience a little blowback. The primers were always dark and there was some residue on the receiver around the firing pin area. The rifle did shoot nice and I especially like the clean up with the new style breech plug with the threads on the out side. The rifle is a little heavy. Equipped with scope, sling and the Warne rings it weighed in at 9 lbs. 2 oz. My Accura MR equipped with scope, sling and Durasight ring weighs in at 8 lbs 4 oz."
