I've loaded S&B pistol primers a few times recently, and noticed two odd things:
1. The seat from easily to scarily easily. Online lore is that S&B brass has very tight primer pockets, so maybe their primers are correspondingly undersized? That issue seems less often discussed.
2. Fired rounds often have VERY flat looking primers from what should not be off-the-charts loads. Their cups start out flatter than some, to my eye, but they finish really flat.
Wondering if 2. could be caused by 1. Would slightly loose primers back out more or faster and somehow get swaged flat as the case head presses back?
