Dillon 1050 primer Kaboom

[tiller]

Yup, I wear Polycarbonate safety glasses behind a full face shield and heavy leather gloves to for primer pickup. You can't replace your eyes. Before I drop the primers into the magazine tube, I take the glove off and touch the press to get rid of any static charge build up. My primer pickup tubes are lined with high pressure air hose tubing to contain any explosion. That's my method.

Lmao a little over board?

This happened. While loading

Not at all, you can't replace your eyes. I want to continue shooting competitively for a long time. And I know a very experienced long time competitive shooter who blew the end of his trigger finger off while loading the pickup tube! That's when I started my method...

What's your method?

That's strange... I have never once worried about this.... Do you have your bench and your press grounded then? There's no point in half assing it!

After reading and seeing the results of grant22's kaboom, I did the same thing to my filler tubes, pics on grant's thread. Of course that was not on a 1050 so things are not quite the same.

That's why I don't do priming on the press anymore. I only do manual priming; one primer at a time. If accident were to happen, it's just one primer blowing; not the whole tube!

It's rare that the whole tube blows.... It takes a lot of things to be right to blow the whole tube...

Go back to college and get your electrical engineering degree, that should only take 5-7 years, if you can even get in. Static discharge does not need to go to earth ground, only to a lower potential. And I bet you grounded your press to an 110 outlet box ground? Which is against most building codes, by the way! Without checking to see if it actually is actually to earth ground and has no potential voltage on it from screwed up homeowner home made wiring? Here is a clue, half ash re-loader, if you actually reload, post pics of your rig. Here is the instrument you need to check for actual earth ground, called a VOM, Volt, Ohm, Meter. You know what that means? Potential and resistance, named after famous Italian physics majors. But since you are soo smart about grounding, I won't describe the protocol for checking true earth ground, you must already know that.

This is an analog unit, there are digital's also. You can google the difference.

You know you don't have to be a dick to everyone on Calguns!

You're in need of a serious attitude adjustment and a time out!

Dude, chill. You can run a lead from the primer pick up tube to the primer tube on the press to equalize the static charge. That is what is commonly called grounded when dealing with static discharges.

but he is a competitive shooter so he is right....

Had a whole primer magazine Kaboom on me this morning. I'm fine. Broke a few pieces on the press.

As I have never had this happen before, and it seems like this sort of thing is probably due to user error.............

What are the normal causes for blowing up a primer and then getting sympathetic detonation of all the rest in the magazine?

This is the exact reason why I do NOT wanna touch these progressive presses and their damn witchy priming systems.

I am gearing myself up for priming via RCBS APS strips and hand held universal primer. Plus, one or two less things to worry about on the progressive presses...- OR turret press for that matter.

Good to hear that you were OKAY in the end. Things like that can knock some folks off the fence I imagine.

I do not think that hose is Battle Rated though...

I was using Federal small pistol primers. I am loading 9mm.

I need to replace the plastic guide/follower rod. It is twisted like a pigtail and left a mark in the ceiling. I need to replace the plastic guide tab at the primer station. I need to replace the inner sleeve to the magazine tube. (the detonated primers blocked it completely) Low primer buzzer assembly has some damage as well.

Yes, wearing glasses. Still made me a little jittery and had to walk away before getting help to tear it apart and see what needed fixing and replacing.

The static thing is interesting in that I had used a can of compressed air to clean the press before I started loading. In the same way air moving over something can cause static electricity I might have done it with the air cleaning? But I doubt it.

After cleaning and taking stuff apart and looking to make sure stuff was all working well I can only guess that I got the one in a million sideways primer that got crushed just right to detonate right where it did such that the pressure wave then started sympathetic detonation of the primers in the loaded magazine tube.

Still I guess my question is unanswered, what are the "usual suspects" when something like this happens?

'Cause I've had some seriously crushed up and goofy looking primers and they've never gone off before. So I really don't know what caused this.

I'd loaded thousand rounds the week before. Same powder, same primers, same cases, same everything.

Just this time on the down stroke about 4 primers in from starting I got an explosion.

My guess would be static. If you read these two posts http://www.calguns.net/calgunforum/s...&postcount=328 and http://www.calguns.net/calgunforum/s...&postcount=339 it might make more sense why I think that a static discharge was involved. I could very well be incorrect though. I am glad you are alright.

Here is the thread that those quotes were taken from, just in case you want to read it. http://www.calguns.net/calgunforum/s...=495909&page=9

It's so much speculation that it's not really worth it but the end of the thread posted above speaks of someone who used to work on the floor of a solid rocket fuel facility which would not work under certain dry situations. There are not enough of these occurrences to have any solid data but basically everything that you can do to avoid static discharges in the primer tube you should do.

Additionally you should clean the tubes regularly to limit dust accumulation.
