- whoops, you already knew what jumping crimp was. That's what i get for reading in a hurry. I'm not sure how many rounds the affected cartridge in your picture went through - was that round saved as the last out of a cylinder of 5? If you want to do more testing you could see how the pulling is after 8 rounds or so. I don't know what the universal rule of thumb is but personally I consider a round that survives almost 2 cylinders without jumping crimp enough to jam to be fairly unlikely to cause trouble in just 1 cylinder full.
