I've been using Mag Tech large rifle primers in my 500 magnum. The cylinder started locking up after every shot and I found the firing pin was stuck and would not return. I put a new pin and spring in, but after 8 shots today it's doing it again. Some of the primers are blown all the way through and others are kind of mushroomed back. I'm thinking that the primers are too soft for this gun and when they blow a hole in them the pin is getting fouled and burned until it finally locks. I'm using a very mild load with Titegroup and I have no problem even with strong factory loads. Any ideas for a harder primer would be appreciated. Thanks
