Can I use small rifle primers in 9mm an 38? I have 4000 and don't have any other use for them. Any help would be appreciated.

Yes. They probably produce more spark than the usual pistol primer and this might increase pressure. Reduce your charge and work up slowly like you would when changing any component.

Dont do it. If this is being loaded for a handgun, alot of handguns dont have enough spring force to set off a rifile primer (they use a hard cup). Plus rifle primers are hotter, which could raise pressures.

Unless you load data states to use a rifle primer (some handguns do ex 454 Casull), dont do it.

Same deal with magnum pistol primers. While the cups are softer, they can raise pressures. If you load is near max - then its possible you will be above Max safe pressures by swapping to magnum or rifle primer.

I accidently loaded 100 9mm rounds with small rifle primers instead of small pistol primers. About 1/3 of the first twenty that I tried failed to fire on the first hammer strike in several different pistols. I pulled the rest when I discovered my mistake.

Try them in YOUR firearms, working up small quans and slowly. You will come to your own conclusion, one that works for you.

I used thousands for 9mm, until I ran into a batch of tula srp with really hard primers.

Small rifle primers in a 9mm 1911 shouldn't be any problem in a factory sprung pistol. They are used in 38 Super chambered guns regularly (mine included, typically Remington 7 1/2s).

I've used tens of thousands of SRPs in 9mm, .38, .40 and .45 with no issues on hammer fired guns.

At least 100K. Lots of folks who reload for .223 use SRP's exclusively for all their loads.
Never had a failure.

Lots of us have the same experience as BillD. Me included.

But it's wise to recognize WalterGC's trouble (post #7) with hard primer cups. Rifle and magnum primers have harder cups to withstand greater pressure. Walter's experience is valuable to recognize.

Most of mine has been CCI SRP.

I think that may be quite significant. I had very frequent failures to fire from the batch I accidently loaded with three Glocks and an M&P. They are striker-fired. I did not have a hammer-fired pistol with me that day. That may be the difference that could be a deal breaker if you use striker-fired pistols a lot.

As suggested earlier, try them in your handguns to see if they will actually fire.

Thanks for all the feed back everyone. I have a STI Trojan so I will try working up a load with them and see if it works.

Shouldn't be a problem with hammer fired pistols…striker fired, not so good.

Sure wished I'd testfired a few, before I did that batch of 5000!!!:rolleyes:

Get a 9mm AR15 carbine for those hard primers. Full hammer strike will ignite them. Or an open bolt full auto :D . That'll work.[aQUOTE]

Had one of our local gendarmes try some in his 9mm AR-type subgun. Lots of misfires.
