There is an easy way to check the bedding. Loosen the front and rear action screws. Now torque the front screw, then tighten the rear screw. The rear screw should go from loose to tight in about 1/4 turn. In other words, it should turn freely then suddenly stop. If it takes a turn or more to come up tight after you begin feeling some turning resistance, your bedding is not right. Now reverse the process and torque the rear screw first and see how the front screw tightens. It should go from loose to tight in 1/4 turn.
If the above checks out and you haven't messed up the recoil lug mortise and your barrel is free floated you can pretty much eliminate bedding as the issue and start looking at optics/mounts.
