Scared myself tonight.... primer story

Yeah, this sounds a little strange.
If the primer was sticking out 1/8" it wouldn't have come out of the priming device. A large rifle primer is 0.118-0.121" tall.
Having a primer so shallowly set in the case will not detonate it on inertial impact. No matter what the OP is stating.

This was primed on an RCBS single stage press. The shell holder is machined right down the middle where the shell slides into it so yes, in fact if the primer was protruding the case can still slide out of the shell holder. I just went and tried it. The depth of this "slot" if you will, is 0.044. You are correct that it is impossible for the primer to be an 1/8 out. That was just a guess while I was still rattled. I did not measure it prior to using the bullet puller. It was protruding enough to catch my attention... which if my numbers are right is less than a 1/16(0.0625) but more than 1/32(0.03125).
 
Is it possible that a piece of media was sitting in the flash hole and detonated the primer? Can a primer be detonated from the opposite side? I have to take a pick and push or pick the media out of the flash holes. The small pieces of media that get stuck there are very sturdy and take a fair amount of force , using a steel pick , to remove. I have to usually push it through. If a piece of the media is stuck in the flashole , measuring 1/16 thereby stopping the primer from fully seating. Is it possible that the force from the bullit puller had enough force to ignite the primer ?

Hmmm, isn't the primer material (the stuff that actually ignites) against the back of the primer? There is quite an air gap between the cage of the primer and the primer material itself.

I just happened to have been fooling around with some macro shots the other night. On the left is CCI Small Pistol primer, and Dominion on the right.

Well somebody got to do an experiment, hit the primer from the opposite side , see if it's possible to ignite from a piece of media. That's the only explaination. :)
 
yup, just tried it. Put a CCI primer on piece of wood, put a nail on the back of it (the anvil). A light tap with a hammer didn't do anything, stronger tap set if off. Lots of flash and some smoke, so make sure you wear gloves and eye protection. I wore ear protection too, but the pop sounded pretty light.

sounds about right, OP said it hit the ceiling. So it popped about 4 feet , not much pressure there:) doubt that would do much damage , unless it hit you in the eyeball.:)
 
i have a older lee hand primer and i noticed as it has gotten older ( primed thousands of rounds) it doesn't seat the primers as deep as it should i replaced it with a newer lee hand primer didn't like it, tried the hornady hand primer liked it less so i'm back using my rock chucker

That and to chance severe injury or death on his belief would be foolish.

How so? I would also think that if the bolt weren't closed when it went of (and mostly chambered), I would be able to hold the bolt closed...it's a rifle round, not a pipe bomb. I really don't see how anyone could get hurt or dead if you are prepared for the potential of an AD.

Wow! You would think it was a pipe bomb you were holding, if the 30-06 fired with the bolt not locked!

Get yourself a ten ton press and try and hold the ram up while cranking the pump.
Heck, stick yer thumb in there and giv'er.

d:h:

YKFS...........
 
uhhh, it's like what, 180 grain pill and an unrestricted muzzle? We're talking about 10 or 12 lbs of recoil, not 10 tonnes. Has no one here ever tried thumbing the slide shut on their semi auto slide? Trust me when I say its anticlimactic, and quite predictable as to where the projectile goes (where ever it's aimed).
 
I suppose not, I've never fired a round on an open breach, I don't even think its possible unless something (lugs) are gone. I also don't think your 10 tonne press is anywhere near accurate. (pretty sure 10 tonnes would sheer those lugs clean off without even tickling the gauge.) It's not rocket science, but it is physics.

You guys say its a bad idea to try to seat the primer with the bolt, ok. Why?...and your 10 tonne analogy doesn't satisfy my valid question. I can't learn if you don't explain.

...and what is YKFS?
 
Well, lets put it this way. That 180 grain bullet will have reached the speed of sound by the time it has travelled between one and two inches.
And you are going to use your hand to hold that kick back?
 
Or you could figure that if the bolt face is about .5", then the surface would work out to .196 square inches. Times that by 60 000psi gets you almost 12 000 lbs of rearward thrust on the bolt face, not taking into account the amount of force that the brass itself will hold. Not childs play for sure.
