1. I accidentally deprimed a case with a live primer in it. I picked it up inspected it, and it looked like normal. So I used it again. But then I just saw the thread about how to remove a live primer and I didn't hear anyone say it was OK to use again. Was it OK to use again? 2. I noticed that my new 550B puts a very small dimple on the center of the primer after priming. It is very slight, but noticeable. I checked the primer seat and it doesn't have any debris on it. The dimple is very very very small but it's there on all 50 rounds that I loaded. Anything to worry about? Thanks Wanna kill these ads? We can help!
