Ok I lost a primer on the floor in the basement.
How powerful is this? Would it take off my whole hand or just a few fingers?
Would I lose a foot of just have a big hole in my heel?

I looked everywhere and can't find it. I'm thinking I need to do a full vacuum/sweep and hope I get it.

By the way, it's a CCI 500 Small Pistol primer that I lost.

if you get it in the vacuum cleaner it will throw the vacuum out of balance when it goes off.

as for how dangerous it is, don't know, but it sure gets my wife's attention when i fire a primed case in a rifle in the house. makes me laugh, makes her jump.

the thing is very unlikely to detonate by itself, though. i've crushed the things in the past w/ no consequences.

They pop pretty good when you vacuum one up and it goes off so try and avoid that if you can. The only danger is if it set the vacuum on fire were my thoughts.
I got into a few live primers one day mixed with hundreds of fired primers I spilled, several went off going through the vacuum before I shut it off. No damage, I did dump the bag in case of something smoldering, and I did get out a carpet sweeper.

Does that basment have a concrete floor? If so, just use a hammer and go around and tap the floor with the hammer. You'll find it...:D

I guess I shouldn't say that...Someone might try that...:what:

I've lost live primers in my loading room on many an ocassion. I have just sweeped the floor and threw the floor sweepings into my wood burning stove in my den and closed the stove door. They don't make that much noise in there and they can't hurt anything ...:)

I've sucked up a few with the shop vac. Don't think there is any problem.

take it like a grain of salt. I mean i try to stay cautious. But i have dropped them stepped on them. i have deprimed live ones. Heck i have even deprimed live primers using a lee classic loader. I have had only 2 go off on me. Thats out of thousands and thousands of primers. So as long as the powder and bullets are not around i would not really worry about it. i would find them personally myself just because i want to load them and use them. but not because im worried.

They might go off if you scuffed your boot-heel on one trying to get it unstuck.
I have had it happen once or twice.

Other then a Change of Shorts being necessaary, no other damage occured.

If you got Rug-Rats, you might want to find it though!

I believe that Julian Hatcher warned against trying to pick
the anvil out of a boxer primer with a needle. A boxer primer
can expel the anvil with enough velocity to put your eye out kid.

What is startling is to seat a primer in a classic Lee Loader using
the primer decappiing punch instead of the primer seating rod. That is
why I developed the habit of decapping all the fired casings first,
putting the decapping punch back in the box, then neck sizing and
capping.

The only thing that makes stepping on one relatively harmless is because your shoe sole contains the flying cup & anvil!

I realize this is this demonstrates my poor judgment but I had three primers ignite in my press. I use an RCBS with the APS system so all of the primers are separated. THe primer seating pin was bent, pobably because I was forcing somethings and when I pushed up on the Winchester small pistol Magnum primer I met resistance. I was actually about 18 inches away from the primer when the primer ignited, with 2 others. I was loud, very bright and I nearly soiled my shorts but I am alive and intact.

I did learn a valuable lesson about using a gentle touch and taking care when the primer does not seat easily.

Would I lose a foot of just have a big hole in my heel?None of the above. That is, unless you're planning to go stomping around in your bare feet looking for it! (That reminds me of an ethnic joke - for a different time and a different board. ;) )

If you happen to step on it with normal shoes, and if it happened to go off (unlikely), I doubt it would cause any noticeable damage to your shoe other than a big sooty mark.

If you use a shopvac type of vacuum, I don't think there's any danger of injury to you or the vac even if it goes off. It's when the pressure is in a tightly confined space that the danger is highest, and also when the anvil is directed at anyone or thing. The anvil will be expelled at very high velocity if the primer cup is made stationary, and at moderately high velocity if it isn't.

One caution however - if the primer happens to off inside a vacuum with lots of dust swirling around inside, there is a chance of a larger explosion. I would clean out the vacuum before using it on your search and destroy mission.


Nothing said above is meant to imply that primers are not dangerous, they are very dangerous especially when quantities of them are involved. But even minimal precautions can take the liklihood of a dangerous situation to practically nil.

I know a fellow who fired the primer in a rifle round by trying to tap it out from the mouth of the case with a nail ground to a point (while he was holding the case in his hand); when the primer fired, the cup went into his hand and travelled under the skin up to the tip of one of his fingers (ring or middle, I can't remember which). They got it out easily enough at the hospital, but it's a demonstration that you don't really want these things firing anywhere near your unprotected body.

Yep!
A primer cup coming out of a primer pocket is traveling probaly close to 1,000 FPS.
Were it not for it's very light weight, it would really do some serious damage.

A friend of mine was drying some empty .38 Special cases in the oven one time.
One of them had a primer in it, and it went off and stuck the primer cup in the top of his foot deep enough he had to have it cut out.

Here is what primers & .22 RF cases will do to an 18ga steel furnace duct.

If a round goes off unconfined, the primer cup, and .22RF, or CF pistol cases are much more dangerous then the bullet itself.

Now why would someone want to pick the anvil out of a primer cup??? That sounds a bit assinine...

I set a Fed 209 off as a kid, and after the pop had warm blood dripping off my chin.

The shredded cup ejected from the rest of the primer, and hit me low in the cheek, leaving a foil like shard about 3/16" deep. I felt absolutely nothing, and until I felt the blood dripping, had no idea I was "hit". I was extremely lucky that day, and have great respect for the power of a lowly primer.

Someone I knew hit a primer, resting on a concrete floor, with a hammer. There was a quarter size hole in the floor about one quarter of an inch deep!!!

Skin and flesh are much softer.

I have got to know why friend was drying cases with his foot in the oven? :eek:

Just to be on the safe side, I use a shop vac and put a knee high nylon stocking between sections of the wand. That way any spilled powder and primers don't end up in the bag. Call it a "prefilter". I do mostly shotgun reloading and shotgun primers will kill a regular vacuum cleaner dead while making one helluva mess when it ignites the dust in the bag and that blows up also.

Mrs Scout was NOT amused.

I have had a bit of a morbid obsession about primers going off.

I have access to a metal shop and some day im going to suit up in protective gear and see just what it takes to set one off.

Totally in the name of science I assure you.

If I push a lead ball all the way into a primed 45acp case to compress the primer.

Shot in a 1911, it will go through a few layers of cardboard and make a loud bang.

My 2-year-old found my press while I was answering the phone.
Got back, the primer tray was missing from my Pro-1000.

WTH?

Find a trail of primers across the room and into the next. He had been carefully picking them up one by one and sticking them into a little plastic cup and shaking them like a rattle.

small pistol primers are not too powerful.
When I started reloading and got my lee classic loader I
got too used to that popping once in a while. Luckily I got myself a Lee auto prime and never since had any pop on me again.
The worst that can happed (unless it pops near your eyes) is that your fingers get blackened by residue and they may hurt a little.
Your ears might ring a little too.

Aren't the metals in a primer ferric?

Can't you sweep the floor with a cow magnet and capture it?

Or am I totally off base?

Mal H

Off base? Nope, you're completely out of the ball park! ;)

I can't say all primers are non-ferrous, but most all commercial primers today are and cannot be attracted by a common magnet. They're usually brass, both cup and anvil.

Take a old pair of panty hose and make a filter/screen from a single layer, put this in one of the hose connection ( if you vac uses a hose) and vac the floor. the panty hose screen will capture the primer in the hose and keep from damaging your vac.

I primed a 20 ga. case and pushed the mouth into a bar of soap. At 20paces I shot it with my air rifle. That primer flew across the room and struck me on the right thigh...2" more left and I would have been a lot more sorry. It really smarted, and when I pulled down my jeans I found a red welt imprint exactly like the base of the primer. VERY dumb.

I still deprime live primers in my single stage press when necessary, but I do it with slow, gentle pressure and have never had a problem. But I have a lot of respect for them, I'll tell ya.

A few inches further right and he would be singing soprano! :eek:

The reason nothing serious happens when a primer pops inside a Lee Loader, or the reloading die on your press is because the flying cup & anvil are contained inside a steel die.

Unconfined out in the open, they can do you serious bodily harm!

Popping primers with a Lee Classic loader was what convinced me to get an auto prime. The small primers didn't bother me much but having a large pistol primer go off kinda got my attention. At one time when I was younger and smoked a pipe I got some #11 caps mixed in my tobacco pouch and having a couple go off in the pipe was a sure surprise. They didn't do any damage just kind of went pop and scattered ashes around. They didn't do much for the taste of the tabacco though.:uhoh:

where do these rumors get started? We can't blame Hollywood because they haven't done a movie featuring the powerful human shredding primer yet.

Primers aren't actually all that easy to set off unless you try. Stepping on them casually won't do it under most conditions, so rest assured you aren't walking among landmines. Sweep them up when you clean up and grab them if you are cheap. With the costs the way they are, I would!
