Well there is a coincidence
I've just been looking up a .45 for a player in my Space 1888 game. I agree with the damage of 16 and I believe the reloading came up on a thread on the AFMBE board.
Edit: I cannot find the thread now so maybe it was somewhere else or my memory is failing....again.
Anyway I think a good rule that  was discussed was that a shooter could reload a number of rounds equal to their Dex in a single turn.

PS. AFOZ is an excellent book but alas it does not have reloading rules either.
