I have a Rem 660 in a 6.5 Rem Mag with a 18.5 inch barrel. (Ya I know that's limiting :-( ) But that's what I got to work with. I just had the action bedded and that helped a bunch. Down to 1.25 x .75 with Hornady's 100 gr Spitzer at 100 yrds. I know one is better with a floating barrel. Usually. But... 1) I'm wondering if the shorter barrel wouldn't work better in a bedded barrel? 2) At what point do you say, OK I'm going to bed the barrel?
