    You use without moon clips any any time of speed loader, 45 acp, or 45 auto rim?

    I know nothing about the .45 auto rim, but I'm pretty sure that .45 ACP will always have to use moon clips.

    The 45 Auto Rim cartridge is just that- a duplicate of the .45 ACP cartridge (usually with a lead bullet) AND with a rim for use in revolvers. It does not need, nor will it fit in, moon clips.

    I recall hearing/reading somewhere that the rim on a .45 Auto Rim is thicker than a normal revolver cartridges rim to compensate for a full moon or half moon clip(s), because the clip(s) require more space in the frame of the revolver.

    Yes, rather thick rim. Guns like the 1917 revolvers had a large gap between cylinder and recoil shield to allow for thickness of the moon clips. The AR cartridge has a thicker rim than most to fill in that gap.

    The .45 acp cylinders on Ruger Blackhawks shoot without moon or half moons clips as they headspace on the case mouth.

    The S&W 25-2 and 625 series (625JM, 625PC, etc.) all will fire .45 ACP with or without clips (half moon, moon, etc.) Apparently S&W decided to lengthen the chamber slightly on the 625s, so that with the normal short firing pin, you can get misfires. I cure that with a longer firing pin. I usually shoot .45 ACP without clips or shoot .45 AR.

    The Ruger NMBH in .45 Colt with the .45 ACP cylinder will also shoot .45 ACP without clips. As they come from the factory they won’t shoot .45 AR, but it is a very easy conversion on a lathe to allow .45 AR to headspace on the .45 ACP cylinder. I prefer to use .45 AR in mine because it seems to cycle more smoothly than .45 ACP.
