[QUOTE="James Jones, post: 142213, member: 8843"] what are your fire forming loads? A severly reduced load can cause pressure problems especialy if the gun is not pointed slightly up of shakken when its pointed up before firing. How much firing pin protrusion do you have when the sear is relaxed? If you pin is sticking out to far it will show signs of cratering where the primer is trying to wrap around the pin thats sticking out to far. In some extreem cases it'll pierce the primer I assume that the chamber is cut correctly? A true Ackley improved chamber is acctualy a bit shorter than standard causing a slight crush fit ,if this is not the case then you might be having some head space issues where the firing pin acctualy bounces the case off the bolt face a tiny bit , generaly this results in the primeres looking flattned out but it has shown to give cratered primers depending on the primer used.
