I'm trying to free float the barrels in my Remington 770 .308 and Remington 700 ADL 30-06 rifles. I thought I had the 770 free floated good but I left the front screw off that goes under the chamber and I think it affected the accuracy. Shots were going all over the place. I put the screw back in and will try again tomorrow. The barrel still is free floated up to the point where the screw goes in.
