Using 454 as 45 colt

Hi all, my first post on this forum.

Looking for input from 45 colt shooters. LGS has Freedom arms model 83 454 in stock. I've wanted Freedom Arms for a while, and would like a 45 colt.

I know I can use this to shoot 45 colt. I don't think I'd shoot much more than a handful of 454's. Is there any downside to using a 454 as 45 colt.

Thanks for responses.
