Ugly reloading precision primer seater

Weirdly enough, I was just priming a couple of hundred cases, and after not using the thing in a while (and because the thing makes it so easy to seat them), I was telling myself "Whoa tough guy, don't want to blow a primer indoors"...

Not saying @K80/6.5 is guilty of it, but double feed or not, I could see how someone could easily go full ham-fisted guerilla and blow some.
So I ran out of primers, went to grab a couple more with the tube and when I put it back on ran the slide and then it went off only thing I can think of is one hung up when I thought I was out and slide it into place and then some kind of way put another one underneath after filling the tube back up. I’m not sure how I did it. But I do know what you’re talking about when it comes to the amount of force you can apply. I don’t know I’m 100% sure it was the operator fault just wish I knew exactly happened to prevent it from happening again. Just thought I would pass it on and even though you might feel like you don’t need to wear safety glasses myself included it’s a good idea to wear them because you never know.

FWIW, I've only used mine with the Vibra-Prime's tube... which fits better and is heavier than a Dillon tube. I don't think mine would double-feed unless I actually tried to make it happen by lifting up and wiggling the tube while shuffling the slider or something.
 
Maybe I will pick some of those up I was using a Dillon tube like I said I know I did something wrong just not sure what it was.

The good old Vibra-Prime rules!

When I'm loading 9mm on my XL750, I fill a tube and then pull the pin and it drops the primers right into the Dillon's primer magazine tube with no fuss, then I fill another one and set it aside until my first 100 runs out... gives me a ~2min break every 200rds and is why my Dillon tubes have never been out of the plastic they came in.

It's a bonus that it's almost like it was custom-made for the PCPS.

I’m glad you didn’t get hurt but also cannot see how one would get two primers in there and how one could go off for that matter without running the press ram up hard and fast. When I seat a primer, I carefully “ease” it in and then rotate the case a seat the primer a couple, three times. I don’t jam it in there hard, which I think all but eliminates the chance for one going off.

I then have a primer depth gauge which I place the case on to ensure my seating depth is consistent. I think using that tool is redundant after awhile but it’s a habit and one of the check boxes on my list of brass preparation, so I use it.

I assumed it was a double feed to be honest I wish I would have taken more time to look closer not going to lie I was in kind of shock. I removed the shell holder because the case would not release. I could have sworn there were two primers in there. Another theory I have was I place the brass in the wrong tray. Possibly I primed that brass already and tried smashing another primer on top of it.

I also use a primer gauge from accuracy one to check seating depth I usually check everyone for the first 20 or so and then spot check after that.
