Welcome to the forum! I have never delt with the accu stock myself but I will try to give you some information that could help you.
First thing I would do is work on what torque your action screws like. Start by torque your front screw to 30lbs-35lbs and your rear to 15 lbs. shoot 3 to 5 round groups at 5 lb increments as you tighten your rear action screw. You should see your groups tighten up and then widen back out at some point. Of course once you find your sweet spot go back to it and fine tune if you like.
Second if if that is not giving you the desired results go ahead and bed the action. Since you don't have to pillar bed it is pretty straight forward. there are a ton of videos and threads on here about bedding your action. I would research until you feel comfortable about what you need to do from start to finish, before you even order anything to start your bedding.
I just completed a pillar and glass bed on my savage wood stock and it turned out pretty good, not perfect, but I am always my worst critic. I spent several months watching videos and reading before proceeding. I could do the whole process visually in my mind before I got started. I was still a nervous wreck when I stuck my action into the bedding compound lol.
Good luck brother!
