great info, thanks, guys.
The revo in question:
FWIW it will be a lightweight knock around the deer lease type gun for me. Probably snake shot in the first chamber & wadcutters in the rest. Good tip on the speedloaders, though, I would not have thought of that issue. I have Titegroup on hand and will use it.
At Manyletters' gathering I loaned it to a friend who was teaching a new lady shooter, and she took right to it with mild loads. So much so I was offered a trade on it, which I had to decline. 3" M60's work well, with mild loads.
