My no-dash 8 3/8" barreled 617 was disappointing for about the first thousand rounds or so- the 4" 617 easily outshot it. But it's now stupidly accurate with ammo it likes. Just took a while for it to settle in, I guess. Had it almost 20 years now. Wouldn't swap it for anything else! I don't even shoot it competitively, just to ensure it retains it's 50yd squirrel getting zero.
