45 Auto Rim

lugerstew · March 3, 2024, 10:21 AM

I have 73ea loaded 45 auto rim cartridges that my cousin bought at an estate sale a while back.
Where can I find a place to post these or find someone who would want them?

I don't have any gun that can fire them, i think they are fairly rare.
Thanks

Anyone with a S&W or Colt, M1917 revolver would probably be interested in them. You can post them below in the Gun Show forums. There's also GunBroker if you wanted to go that route.

Verifiable factory loaded rounds or reloads?? Original factory box(es)?? Makes a difference in what they're worth.

Gunbroker is your best bet.
Specify reloads or factory.
Otherwise, you may have an unhappy buyer.

They won’t fit in 45 Colt, right? Due to that thick rim??

They are in a Ziplock bag, they look to be factory, but how can I tell? I guess I will get my strong magnifier out and look for resizing marks or something.

45 Auto Rim will not chamber in a Colt with a . 45 ACP cylinder. The rim is too thick to fit through the gap.Oct 3, 2022

The .45 Auto Rim was introduced by the Peters Cartridge Company in 1920.
It was specifically designed to work in the 1917 Colt and S&W .45ACP revolvers. The large thick rim means the round does not require clips to work in those guns.

It does not fit in other .45acp revolvers, the rim is too thick.

Last time I looked the .45 Auto Rim was still listed as being an "in production" round. That doesn't mean it is being produced every day, today, production of many rounds is "seasonal", meaning they are made in batches, not constantly. When the inventory reaches a set low point, the factories set up the tooling and produce X number of rounds, then pack it away, again, until the next time.

The only factory .45AR loading I'm aware of is a 230gr LRN.

Lack of resizing marks on the ammo you have is not proof it is factory ammo. Without the assurance of the ammo being in a factory box and looking correct, it should not be sold as factory ammo, and should be offered for components only.

Thanks 44 Amp,
I guess since i could never prove these were factory rounds, I should just dispose of them in a proper way.
Thanks so much for all the professional help on here..

There is no reason you can't sell, trade, or give them to someone who wants them, just be clear they are "as is, origin unknown" may not be safe to shoot, and should be pulled down for the components (cases, perhaps bullets).

If you have the tools, time, and the inclination, you could pull them down and toss the powder, removing any risk of them being used as ammo.

Bullet pullers aren't expensive. You could buy one and break them down and sell them as primed cases and the bullets. Buyer supplies their own powder and would be happy to have whatever cases you have available.
