I have the Rossi R92 and with 125gr Flat Points and 17.8 grains of Alliant 300-MP we were consistently hitting the mark on pretty long shots(over 100 yards). That load is super dirty in short barrel revolvers though
The sights that come from teh factory aren't all that great according to most people I've talked to. The rear sight can shift a little left and right, the rear notch can give off a glare(and it's what I blame for my missed shots
) and little other things that you can adjust to given 100 or so rounds.
