RE: case bulge near base

Is there an expected life for these plates? Seems like I replaced mine not too long ago and it is worn out already.

RE: case bulge near base

The lifespan varies, with a tapered case like a 9mm and large cases with a considerable surface area, such as a 45 Colt, wearing out sooner than a shorter straightwall case , such as a 38 Super, 45ACP. Usually they start to display detectable wear at about 35,000-40,000 cycles for the cases that cause more wear.
