I was just looking at it and couldn't figure out what the "R P" stood for on the Remington UMC ammo. Just curious and wanting to know.

Peters was bought by Remington and became Remington-Peters. UMC is Union Metallic Cartridge.

Old .45 Brass

I have .45acp Brass with those old headstamps and they are in good enough condition to shoot. .

Have some 38 experimental stuff with plastic cases, 38/44 cases, rimless38's and large primers hole .38 cases

I've got a "Peters" only .45 ACP case kicking around somewhere. That probably puts it at 50 years old or more.

Old Peters blue and white box with red symbol is about a thing
of the past, as you don't see many of these any more.

The oldest Peters ammo I have in my collection/stash are a couple of boxes of .45 I have both 185 SWC and 230 gr hardball. The headstamp is Peters .45 Auto.

Peters Rustless priming was the exact same thing as Remington's Kleenbore. I have some Remington ammo from the same time period (early 1950s) that are headstamped REM-UMC.

I fired a box of the 230 gr about two years ago and fired 20 rounds over the chronograph at around 875fps. I think the variation was less than 15fps.

My box of Peters .41 magnum is headstamped R-P. Notice that Peters had ditched the Rustless name and gone with the more recognizable Kleenbore Priming.

I paid $9.50 for the entire box at Seller's Hardware in Okolona Kentucky in 1978.
