Large rifle primers in .45ACP

rdan · October 30, 2001, 10:09 PM

Accidently loaded CCI#200 large rifle primers
in some .45ACP brass. Will this be safe to use
with standard pressure loads or should I
just get rid of them? Anyone else done this?

The rifle primer is considerably hotter. You might get away with dropping the load, but gods alone would know how much...

And the accuracy would suffer.
Probably best to get rid of 'em.

Large Rifle primers are deeper than Large Pistol primers. So, either the primer protrudes somewhat, or the primers have been crushed a bit in the seating process.

LR primers are harder. The "cup" is physically stronger and requires more of a hit to set it off.

One can de-prime live primers, but is universally discouraged. At best it is nerve racking. Depending on how many cases you have, you can salvage the cases by dropping a bit of oil in each case and letting them sit overnight.
Then you should be able to de cap and discard the now enert primers.

If the rounds are to be fired in a well-supported chamber, there will be no problems if the priimer is flush or slightly below the head.

I've done this before with a Springfield standard .45. No overpressure and more than acceptable accuracy. Remember 1994's primer shortage? Yes, I was using rifle primers in my .45 because that's all I could get. My backordered stocks arrived in September after being on order for 3 months!

I have used large magnum pistol primers in my .45 but never large rifle... Interested to see what this would do..

The large rifle primers are no hotter than pistol primers, but they are .008 inch higher and will not seat properly.
I'd go ahead and seat them flush and load them. I've used them before in .44 cal ammo.
If you can't seat them flush, then kill them with oil and resize.

FYI, small rifle primers are the same size as small pistol. I use small rifle primers for all my small pistol loads.

Rifle primers are a bit harder than pistol primers.

then I would suggest pulling the bullets then firing off the primed brass in your pistol so you can recover the brass.

Anyone know why this wouldn't be ok to do?

In any case, thats what I would do.

as usual, IMHO, YMMV, FWIW, and all that...

Two reasons:

First, chambering a bare case is a bear. If you insert it into the chamber, you risk damage to the extractor. If you could chamber them in a revolver, then you could safely fire them in a pistol.

Second, do it outside. There's lots of lead in the primers. Its quite dirty too.

Pull the bullets & just resize (which will remove the "bad" primers). Wear a good pair of safety glasses - ear plugs might not be a bad idea either.

Just go about it slowly when you feel the decap pin contact the primer.

I've deprimed a ton of live primers & have yet have one go off.

in using LR primers in a .45 ACP. To correct a cratered primer problem in my .45 Super, I switched to Federal 210M primers. I DID deepen the primer pocket by .006"using a Sinclair Primer Pocket Uniformer. In fact, standard deviation dropped from 14 to 4.5. Average velocity actually dropped from 1,132 fps to 1,103 fps with the exact same powder charge.

That is an interesting post - TFL does it yet again!.

Locally many Hornet and .222 fans download for less noise in urban areas and use small pistol primers which do the job and are 1.7c as opposed to 3c from our supplier.

I suppose a 44Mag Rifle could use LR primers -though it is a pistol calibre....but I have always used LPs...interesting as I thought [with a 180gn and 25gn AR2205] the Federal LP primers were getting a bit difficult to press out.
