Making 45 Auto Rim from 45 Long Colt brass??

[WHG]

I have a Webley 455 revolver that has had it's cylinder shaved so that you can use 45 ACP or 45 Auto Rim in it. 45 Auto Rim is expensive and not that common. I have lots of 45 Long Colt and was thinking of cutting it down to the length of 45 Auto Rim. 45 Auto Rim is loaded pretty much the same as 45 ACP, which is under much less pressure than 45 Long Colt. So, I don't think there would be an issue with the brass being able to handle the pressure generated with a 45 ACP load. The only issue I see is that the rim on the 45 Long colt is .060 and the Auto Rim is .090. Does anyone think this would be a very bad thing? I always shoot light loads in the Webley, just plinking to have some fun.

I think your going to have some problems using 45 Colt brass in your shaved 455 cylinder, better to buy some 45 auto rim to eliminate any headspace/ignition problems. The 45 Colt can be cut back and turned-down to use in the 455 Webley auto cartridge

can you use c clips and 45 auto ??

The difference would allow the LC cases to move too far forward. You could have misfires and/or gas leakage problems and/or streached cases. Would not do it if it were me , and I do a lot of stupid stuff.

I don't know how much you shoot this revolver, but 21 bucks for a 100 brass doesn't seem to bad to me??

as noted above, you might also try half-moon clips, but (again) 21 bucks..

A friend gave me two boxes of (new) .455 brass, so instead of changing cylinders in my USFA (Rodeo) to the .45 acp cylinder, I just use this brass to make up "light/plinking" loads (5.2 grs W231 and usually 200 SWCs).

BTW, there ain't (really) any such thing as a .45 "Long Colt." It's just a .45 Colt.

While "45 Long Colt" may not be an official designation I bet that every GI and cowboy used the term to differentiate it from the shorter 45 Schofield and the 45 Govt cartridges that were available in the local hardware store and issued by the Army. This could be important as the Schofield's larger diameter rim could interfere with loading in some Colts and the Colt round was too long for the Schofield. The compromise 45 Govt was just a shorter version of the Colt so it could be used in both revolvers. Hence there was indeed a Short and a Long version of the 45 Colt so the term 45 Long Colt has historical validity.

45 S&W Schofield/45 Government NOT

45 Colt black powder

45 Colt Govt Model 1909

I don't know where you borrowed that picture, but (AFAIK) the .45 Schofield/S&W NEVER came in RIMFIRE! The round on the far left isn't using a heeled bullet round, but I suspect it is a .44 Henry??

PS: People can call things whatever they like, but the "LC" thing always makes me cringe a bit.

That is not a rimfire round. That's an inside primed centerfire case. You can tell by the crimp near the base of the case that locks the anvil inside the case.

Thank you Jerry,

musculus, you need to study these 45 cal cartridges a little more.

anyone notice the extra large rim diameter on the Govt 1909 cartridge / difficult to load the single action Colt as you can only use ever other chamber.

I am always open to new information, but whether or not I "need to study" collector/rare cartridges or not is a matter of modest indifference to me.

the early cartridges

musculus:

photo shows 44 Henry rim fire, 45 Govt , 45-70, 50-70 last three are inside primed

Now you can tell the difference

Let's put it another way, Musculus. You might consider learning more about early metallic cartridges before speculating about items with which you're unfamiliar. Image below comes from chapter 3 of Sharpe's Complete Guide to Handloading, available for download if you're willing to do a little searching.

Maybe you don't need to study, but you do need to know what you are talking about before you tell someone else they are wrong. The cartridge is benet-primed, and can be readily identified by the crimp just above the rim which holds the primer assembly in place.

When Ordnance ordered the Model 1909 Revolver as an interim larger caliber weapon while what became the Model 1911 was being developed, they didn't think the ejection was positive with the tiny rim of the .45 Colt, so they had a cartridge made with the larger diameter rim, and as noted above it would only work in every other cylinder of the Colt SAA.

In recent history the .45 Colt rim has been modified somewhat by rebating the rim to aid in extraction in some of the lever guns that have become popular in the .45 Colt chambering.
