Here's another option from H&R, the model 603,604.
Double action, swing cylinder, 6 shooter, heavy barrel.
The same revolver, except one has round barrel, the other has flat sided barrel.
No longer made, but they are found quite often on the 2 main auction sites.
Actually one of them has at least 2 very nice examples listed right now.
Here is a pic of my model 604.
Bought it unfired in box for the excellent price of $ 165 plus shipping.
Got lucky on this one, and no one else bid.
Still have not fired it, so can't speak for how it shoots.
