WHAT happen

[TOMtumtum]

Hi a friend was pulling bullets with a hammer stile puller and a primer went
off had to go to the dc to take it out of his head . why would the impact set
it off he has the primer there is no dint in the primer just his head

Stop banging the primer into the cement floor.

The primer went off but the exploding cartridge didn't blow the bullet puller to bits?

There is no way a primer can detonate from the proper use of a kinetic bullet puller.

Kind of hard to understand what the OP is talking about on the first read... especially that last part.

With the collet puller type in your press, that kind of thing never happens!

Sorry about the bits in your friends head.

You would almost think he hit the wrong end of the hammer into the floor / surface.

This sounds like a classic case of RTFM.

The cartridge won't explode, or even fire, if its not in a rifle. The primer will just pop out of the cartridge, like it did.

Primers are detonators. Nothing is fool proof.

If the primer was not seated correctly, the kinetic force could have slammed it into the pocket, crushing the anvil into the bottom of the primer cup, making the whole works go POP. Not a common occurance, but obviously possible.

Either that or Darwin was hitting the wrong end of the hammer on the floor Although, if He HAD been hitting it backwards, the primer would have been sent into the floor, not his forehead. Unless he was hitting it primer first, ON his forehead

You know, reading the warnings that things come with these days, nothing surprises me anymore.

What cartridge? Not that it really matters, just curious

Sorry. Double post. I should have gotten a faster computer last year but I bought a pistol instead.

Seems to still work, better buy another pistol with this years computer money. When you can't post anymore, then you need a new computer.

Caution. This Superman costume will not allow you to fly. Do not jump out of the window....

Which end of the bullet puller was he hitting against the ground?

After the gunroom gets a facelift, a Dillion is next on the list but that is for another thread.

Was the ammo that he was pulling Berdan or Boxer primed?

it off

Bad luck. Coupled to the poor sense to have his head in the line of fire if it did go off.

Uhhh NO! If the primer goes, it will ignite the powder and the pressure will cause the case to rupture. That is after all how the thing works. The only difference would be that the pressure is not contained by the barrel. To suggest that a detonating primer would simply pop out the back of the case shows a distinct lack of understanding of how the whole thing works.

I have a couple of friend's with old shrapnel wounds as proof that a cartridge can in fact detonate outside of a firearm. You just have to do something stupid with it.

No, not possible at all. The primer cup is seated on the bottom of the primer pocket so it cannot move forward. The forces involved with a kinetic bullet puller would actually pull the anvil away from the primer cup. The primer cannot detonate unless the wafer is crushed between the cup and anvil and that can only happen if the cup is dented like when a firing pin hits it.

Can't believe I am saying this twice in one posting but your comment shows a distinct lack of understanding of how the whole thing works.

Well, his primer DID NOT ignite the cartridge, so your theory is not 100% either. And apparently, my theory was closer to being correct, because the primer DID pop out and hit him in the head.

Unless you were there to witness this event and have more knowledge of it than the rest of us?

 

[curtmg]

So, Professor Saputin, please enlighten us on what REALLY happened. And explain why my bullet hammer manual had a warning about such a thing happening. It's been stated that I don't understand how the whole thing works, and I'd like to understand.

What I said is that the primer is NOT seated properly to the bottom of the pocket, so that it is moving under kinetic force, hitting the bottom of the pocket, or possibly some debris within the pocket, with momentum, causing the primer to fire. I'm not being argumentative, I just want to understand what part of my theory is wrong.

OK, I have no idea how the primer could possibly be detonated by using an inertia bullet puller.
However, I do know something about cartridges being fired ouside of a rifle. In the good (bad?) old days it was very common to set a loaded cartridge on a stove, in such places as a hunting camp, or some other place where men were isolated for considerable periods of time, living in some remote cabin and just ran out of other sorts of amuzement.
So, from the horses mouth, here is the skinny on it. A loaded cartridge sitting on a hot stove will, in something up to half a minute or so, depending on how hot the stove is, will detonate the primer. And when the primer goes off it ignites the powder. The rifle case, be they 30-30, 303 or 30-06, usually didn't ruptre, and at this late stage, I can't say for sure if any did or not, but I don't think so. The bullet would fly out, hit the roof of the cabin and go bouncing off somewhere. To be safe, the people doing this would be on the bed, which in the type of cabins I refer to, would be only maybe 8 feet from the stove, and but a blanket between them and the stove. The bullets would barely make a mark in the board roof of the cabin. Usually not visible of where it hit.
And a bit of a surprise, 22 long rifle would go off nearly as loud as a 30-06 and pieces of the case would fly around the room.
