Uh oh, just primed some handgun brass with large magnum rifle primers

[Tomas]

I'm usually so careful, but I blew it tonight.

So, what do I do with them. It's about 30 rounds. No powder or bullet, just the primers are in the brass (10mm). Could I still load them up with a lower pressure load? Or, do I drop them in my SW 610, shoot the primers out and start over?

I'd just run them through a deprimer (aka, first stage die) and reprime. Done it many a time...just move the ram a tad slower.

[layusn1]

Yup, only 30 rounds...go for the resize die and pop them out really slowly. I go until I feel the pin hit the primer and do a slow 3 count to pop it out. Might want to wear hearing and eye protection just in case. I have screwed up, I mean had to deprime about 200 rounds now and haven't had a problem but still, better safe then sorry.

[VaFisher]

Being on the subject, how much difference would the two primers be and would it be safe to shoot as is or would it be dangerous to do this.

[lockedcj7]

huge difference. Don't do it. De-prime carefully wearing safety glasses!

[brickeyee]

Large rifle are taller than large pistol.
Just knock them out with a depriming die, and pitch them.

[Mike Irwin]

I would not shoot them.

Large rifle magnum primers are quite a bit more energetic than large pistol primers. They're designed to ignite large quantities of slow burning powders.

You could potentially run into serious pressure excursion problems if you were to use them with pistol powders, which are much faster burning.

[Art Eatman]

If you're worried about depriming "live", just shoot them as if they were blanks. If you're at home, just go into a closet and aim into a bucket; you might bother to drape a towel around "the system". Wear your hearguards.

Nobody will ever know...

In the closet and shooting blanks........... The whole emasculated H&H thing is really affecting this board to it's detriment.

[jamaica]

Definitely DO NOT load them.

I would carefully deprime them as suggested. Wear your safety gear.

[James A. Mullins]

Pop them off with the gun, then decap and reprime. I know many people who have deprimed live primers. They flood the bottom of the case with WD40 throw a heavy rag over the press and de prime. The safest is pop them in the gun. Good luck .

I've deprimed many cases on my 550, with no ill effects. One must obviously be gentle, but not only do I deprime without disaster, I can catch the primer as it comes down the chute and re-use it.

But that's me; you may wish to do something else.

[mattgreennra]

I've deprimed S L O W on my RCBS rock chucker before. No problems. I wouldn't try to re-use them. If you scrap old primers you could always go outside with a hammer and pop em all w/ earmuffs on, that's what I do when primers get "compromised."

[mtnbkr]

You could always use them for wax bullet loads for shooting in the backyard or teaching newbies.

You'll get *some* utility out of them.

I'm sitting on about 1100 CCI SP mag primers and no immediate use for them.
Is there any way I can safely use them up in some reduced .38 special loads somehow?

[mtnbkr]

Years ago, when I was just starting reloading, I only had SP Mag primers on hand because I was mainly loading 357mag loads. Then, I decided to load some 38s as well. I used the mag primers with a slightly reduced powder charge with no problems at all.

I keep both types on hand now, but in a pinch I'd use the mag primers again for 38 Special loads. It's not "best practice", but it works.

[Edward429451]

So what'd you do drop a grain off the starting load? 2 grains?

I have Unique, Bullseye, Power Pistol, and 231 on hand.

Agreed, not the best practice to do this, when they're gone, they're gone. I just don't have a clue what they'll do pressure wise and these would be shot in a non +P rated gun. Sure would like to use them up though.

[mtnbkr]

Not even that much, half a grain or so below max (standard pressure data, not +P). They were just plinking loads. I shot most of them through a GP100, but also shot some later on in a S&W M36. I never noticed any problems that indicated I needed to change the load.

This was with Bullseye.
