625-4

Peakbagr · February 18, 2025, 06:32 PM

I ended up finding the gun I was looking for a few years ago. Shoots a .45 Auto Rim with moon clips. A shooter friend told me I could could shoot .45ACP in the gun if I loaded them with moon clips. Anyone know if that's correct?

Yes, 45 Auto Rim or 45 ACP with or without the clips.
Edit:
Buffalo Bore offer's some serious 45 Auto Rim although kinda expensive.
Starline has 45 AR brass readily available.
You also have, half moon 3 round and 2 round clips available for shooting 45 ACP.

So much BS out there.......use Auto Rim or and 45 acp with clips..........I have 4 so 1/3-1/2 or full moon clips or auto ........3 in shown with Auto Rim

Auto Rim brass eliminates the need for any clips, why Remington designed it over 100 years ago.

No. The Auto RIM is so you can shoot without the clips meant for .45 ACP from 1917 on.

As others already said, the Auto Rim exists solely to eliminate the need of moon clips.

The .45 Auto Rim was introduced by the Peters company about 1920, to allow easy, convenient use of the Colt and S&W 1917 revolvers without needing to use clips.

The rim was made extra thick, to take up the space in the gun needed when using ACP brass and clips.

Guns made to use clipped .45ACP can use .45 Auto rim. Generally, guns modified to use ACP brass with clips, (such as some Webleys) often will, but may not. Guns made to fire .45ACP without clips, such as single action revolves, cannot use Auto Rim brass (there is no room for the thick AR rim).

Your 625 was made to use .45acp with clips for simultaneous extraction and ejection. It will fire acp rounds without clips, but you have to remove the fired brass one at a time.

You cannot use Auto Rim ammo with clips in your gun, there isn't room, and the acp clips are made to go in the acp case extractor groove, which the Auto Rim does not have.

.45ACP (with clips) OR .45 Auto Rim (without clips) is what your gun is made to shoot.

Good explanation!
To add, if your fingers were strong enough to squeeze an Auto Rim into a moon clip it would probably destroy the clip or the brass or both.

I used a pencil (eraser end) to remove empty brass from the clips in my Model 25-2 Smith. My revolver came with a second cylinder chambered for 45 Colt. I have not used the cylinder for 45 ACP since 2010. It's a pain to use and the 45 Colt is a better caliber.

In any case if you only have the 45 ACP cylinder the 45 Auto Rim is as good a solution as any.

The Rimz plastic clips can be loaded and unloaded bare handed.
They say their 625 is easiest, the 25 has better retention.

You can go clipless and poke the empties out with a stick. I have read but not seen that some of the stainless guns have deeper chambers and may depend on a clip for headspace against the hammer fall.

The Auto Rim has the advantage of no clip needed.
The ACP has the advantage of a wider variety of factory ammo.

Full moon or other, allow to load more than 1 round at a time with ACP. Otherwise Auto Rim means loading 1 at a time!

Pumpkin · February 21, 2025, 06:41 PM

I believe all Smiths are chambered for 45ACP therefore clips are needed only for ejection of the cases. My 625 will allow you to pick out the cases with your fingernails.

**44 AMP** · February 23, 2025, 02:44 PM

From the 1917 model on, all S&W .45 ACP revolvers have been made with a "ledge" in the chamber the ACP case can headspace on. They load and fire without the need for clips.

Clips (2, 3, or 6rnd) are needed for simultaneous extraction and ejection. Yes, they do function as a kind of speedloader, but their designed intent was to be a "speed unloader", so fired brass didn't have to be picked/poked out one at a time.

"Auto Rim brass eliminates the need for any clips, why Remington designed it over 100 years ago."

Peters, actually. They introduced the .45 Auto Rim in their 1920 catalog.

Remington-UMC didn't purchase Peters until 1934.

For me, the .45 AR is a lot of fun to use, across platforms. I use it in my S&W 625, and I use it in my Ruger .45 Colt NMBH with a .45 ACP cylinder which has been modified to allow the use of the .45 AR. I can load both .45 ACP and .45 AR on my Dillon 550 by just switching out the shell plate. It turns out that .45 AR is very accurate in the NMBH as well as the 625.
