[QUOTE="25WSM, post: 1780303, member: 38048"] The way I'm reading this is you have an established powder charge you use. And this charge works in your lrp brass. Then when you put that same charge in your srp brass it pierced the primers. If this is what you are trying to say then it's probably that the srp brass has less volume and therefore creating over pressure. You just can't take a load that works in one brass and put it in another and expect it to work. You need to work up the load for your new srp brass. You just can't mix and match any components up and expect it to work. Always drop back down on charge weight and work back up to a safe load. Pierced primers are almost always caused by too much pressure. A loose firing pin fit can do it if you run too much pressure. A firing pin protrusion of 50 to 65 thousands. Different guns will have different specs on this. Try backing down the charge weight and working back up to max. Shep [/QUOTE]
