    I recently got Blackhawk in 45 LC. I know the didifference between the LC and ACP, but, where does the .45 ar fit into the scheme? Or, is there a .45 ar?

    Yes there is, 45 Auto Rim.
    It is a 45ACP with a rim on the back to avoid having to use moon clips in 45ACP revolvers. You can shoot 45 AR in a 45ACP REVOLVER without fussing with the moon clips. Great for the range. I understand that reloading for 45 AR (if you are already setup for 45 ACP is pretty painless.

    The 45ar has nothing to do with a 45LC. A buddy sent me an article about the 45AR but you wouldn't want to read it. It slams the 45LC cartridge the whole time. Don't worry, I have one too. Except mine also chambers 410 ga shot shells. :cool:

    If I had a 45acp snubbie to carry I would keep it loaded with 45ar's and have a moon clip of 45 acp's for a reload. But that's just me.

    ...which is downright silly.

    You can shoot uploaded .45LC cartridges that have 325 gr. bullets and the muzzle velocity of maxed-out .44 Magnum, in a Blackhawk. They're even available commercially.

    Don't try that with a .45ACP (or the rimmed version).

    And at the same time, the .45LC is a proven performer in CAS matches, with very low recoil target rounds, as well.

    That's not to diminish the utility of a snubbie in a stubby but powerful round like the .45 ACP or AR. But it's hard to see a justification for slamming the .45LC -- for certain uses.

    I didn't say that I agree with him. :neener:

    I guess I wasn't thinking about the fact that the Blackhawk is one of the guns that won't blow up with those crazy hot and heavy rounds in it. I like the 45LC personally I just wish they made more of the guns that would handle the true capacity of the cartridge.

    .45 Colt is great in strong revolvers when loaded to standard factory power or greater (up to +P type loads). For low power loads like CAS loads, you have a great deal of empty space in the case. That makes for inconsistency at best. The .45 ACP and .45 AR cases are much smaller and can be loaded with light range loads more consistently than the Colt case, and they can handle loads up to the standard factory .45 Colt loads.
    In S&W N frame revolvers, you don’t get much with a .45 Colt that you can’t do with the .45 AR due to the strength and durability of the gun.
    In the Ruger Blackhawks, you can get a .45 ACP cylinder, but without modification, .45 AR won’t work. Currently, in you want to shoot a rimmed, short .45, you have two choices: use rimmed .45 Cowboy cases which are .45 ACP case size with a .060” thick rim, same as the .45 Colt, or you can have the cylinder trimmed to allow the use of the .089” thick rims on .45 AR cases.
    I had several .45 NMBHs with .45 ACP cylinders trimmed for use of .45 AR. Now I can use the same loads in my NMBH as I use in my 625-8JM. I don’t have to fool around with moon clips and I don’t have to pick .45 ACP cases out with my finger nails, but I retain the capability to use the .45 ACP with both guns.

    Now I remember (with a little help!). thanks,
    I have been shooting ACP in my SW 625 with moon clips for so long that I totally forgot AR=auto rim. I like the ACP cartridge because it is moderately cheap and I only have to buy one cartridge between the 1911 and the 625.

    I thought that the CAS ammo problem has been solved by more than one powder maker. Has it not?

    (I used to do COW loads in a BP revolver to save money on Pyrodex.)

    Oh yeah... COW stands for Cream-o-Wheat.:D
