I have a bone stock 11vt that off a bipod on the bench can shoot in the .44 area center to center at 100 yards when I do my part and the stars align. The rifle caliber is 223 and the best groups are with handloads. I haven't had the opportunity to stretch farther than that yet but plan to. My question is do I get any appreciable return on investment if I were to change out the stock? I'm thinking a bell and carlson m40 or waiting on the new savage chasis from oryx. Thank you in advance for your opinions on this matter.
