Yeah, any revolver chambered for .45 ACP is also chambered for .45 Auto Rim, so it can't be claimed that you're shooting a "different cartridge" or one for which the gun was not originally chambered, but that doesn't mean the rules addendum wasn't intended to prevent doing it. There have been a number of instances of IDPA making specific rulings that are contrary to either the spirit (moving 10mm from CDP to ESP) or the letter (banning the STI Recoil Master guide rod) of the rules, so it's hard to say if they're trying to keep people from shooting downloaded .45s in SSR with this new rule.
