Thanks! How many times can you dry fire against one snap cap before you need to replace it? or does just one last forever?
In the past, I have gotten cheap cast plastic snap caps and they didn’t last very long at all. The firing pin quickly pounded a dent in the “head” that was as deep as the firing pin’s full extension. At that point, the snap cap might as well have not been there. I currently use machined aluminum caps with a piece of silicone rubber where the primer would be on a live round. They show little wear even after heavy use. I have no idea how long they will last, I just check for wear and damage.
