R P headstamped brass - Any good?


May 24, 2010, 09:46 AM
I have about two-hundred 45acp brass headstamped R P. I found out that it's remington, but is the brass worth my time?

Anyone reloaded these before?

RP is Remington-Peters, and if in good condition and not rusted up is as good as any other reloadable case available. Maybe even a little better. :)

45 is pretty low pressure, for 45 I use it all with the exception of steel and American. Remington is good to go:)

I stopped using the remington .223 a few years ago because I found the bases to be a bit soft and I ended up with a ton of LC.

RP works just fine in reloading .38 spl & 357 mag.
So I'd venture to say it should be fine for .45 acp as well.

It's crappy brass....send it to me for proper disposal.

It works just fine. It tends to run a bit thinner than most. Check to make sure you still have good neck tension with it. If so, you are good to go. I have three .45 ACP sizers, one of which is too big to work with RP brass.

Full Metal Jacket--i second Walkalong's post re. R P brass being on the thin side. As BTP pointed out, the .45 ACP round is a low-pressure affair, so it's not as critical as it might be.

If you can resize the brass, and taper-crimp it to hold the bullets (I use lead bullets, for bullseye shooting; that's where my experience with the .45 lies) it should work just fine.

You've already got the R P brass so price is not a consideration @ this point. I'd not pay $$ for any more of the stuff, though. (I never pay for .45 ACP brass--I have enough free range pick-ups.)

Frankly my supply is large enough that I'm gradually culling the R P brass specifically because of the thinness--with bullseye shooting you want everything as completely equal, shot to shot, as you can possibly manage. But I'm still loading everything else, except of course steel, Al, and Amerc brass.

Keep an eye out @ the range; scrounge whatever you can, and soon you'll have a nice collection of Win, Fed, Fiocci, Speer, and Starline .45 brass, and you'll see that all of that has thicker walls than the R P stuff.

Somebody on one of these gun-users' fora did a study on brass longevity a while back. IIRC, the R P brass lasted for several reloadings before the lot began splitting, wheras everything else lasted for more reloadings. I'm sure the thin R P walls were a contributing factor.

Thanks Smokey Joe. Im set then, The Rem brass was free range pickup anyway. I'll just use it for plinkers.

Don't use it! :D It's horrible. :D It will ruin your press and your gun. :D The spirit of Gershon Peters exists in every cartridge, and will never rest! :D

Send it to me, and I will lift the spell cast upon it. :evil:

Or, you can use it at your own risk. :neener:

R-P is my second most preferred brass, actually, after Starline. It's thinner than Starline, but more consistent than others. Federal, PMC and a number of others, you can feel the difference when taper crimping.

I've used it extensively - in .45 Auto, and .223, both pre-primed, and un-primed. I'm on my 2nd loading in .45, and my 3rd loading in .223. I like it. It hasn't grown much, if at all, in the .223; but admittedly, I don't load very hot either. Brass came from the factory pretty uniform, and primers seemed to go in with mild effort.

If it's in load-able condition, I'd use it.
