I don't shoot competitions (apart from the fun Xmas type stuff) as I find that it spoils my enjoyment, however I do shoot alongside some former international shooters and they all seem to run very light loads in rifled repro handguns. Smooth is a whole 'nother matter - those guys really stoke 'em up!
I use an even lighter load in my Uberti Remington, but a previous owner had it "breathed on" in various ways, including cylinder timing, lapped barrel, and a very small cylinder gap, so I don't think that citing those loads would be very helpful.
Give it a go - the price of powder these days.....!
