: Ahh, now I understand what you mean.
: The .45 Auto Rim, the .45 AR, is just a .45ACP with a slightly bigger
: rim (2mm, I think). During WWI, when the .45ACP was used for revolvers
: as well, the hlafmoon clips were extremely disliked by the US soldiers.
: When the first World War ended a private company (Peter's Co???)
: manufactured the .45AR.
: The .45 Auto Rim actually stands for .45 'Auto'matic 'Rim'med. So it
: has nothing to do with rimfire.
: In general one can say that there are no differences between the two
: .45 calibres. However, I think there are differences in reloading...
: Maybe Michaelson can give you better information or make clarifications
: because this calibre is relatively rare where I live and I don't know
: much about it. I've never had one in my hands.
: Anway, it would be an interesting question if Indy used halfmoon clips
: or the .45AR...
Sorry for the mix-up, rim-fire, rim, my mistake. I am not as well-voiced in the handgun terminology as perhaps you and Michaelson, and certainly I do my father (who's owned guns all of his life) no justice when I try to relay what he has told me. I don't know about the scarcity of the brass, but he did order 1000 of this brass from a dealer near him, so it is apparently available, and I don't think he spent a fortune on it.
It is interesting that we all have automatically assumed that Indy was firing .45 and not .455. I think if the actual prop was a .45, they may very well have used the auto rim since when he breaks open the gun on the beach to see if he has ammo left, there is no evidence of the half or full-moon clips, indicating either .455 or .45 auto rim. Again, my untrained opinion.
