How's this?

I still have the 14" Contender barrel, and it's still one of my favorites. The Model 94 is long gone, though.
I'd lean to the 120-gr bullets simply because of the slightly higher velocity and flatter trajectory, but there's nothing wrong with the "thump" of the 140s.
I shot 'em all and now seldom load anything but 120s in mine. It keeps the sight-in situation a lot simpler, too.
