I have a 10/22 SS with a barrel that measures 920 at the breech and 707 at the muzzle. The stock is what appears to be original issue wood. I bought the gun used so I'm not 100% certain that it is abosolute stock but it doesn't show any signs of having been modified. I get consistent 1/2 inch groups at 25 yds and am looking to improve on that. I am reluctant to float the barrel because there is only one screw that secures the stock to the action. Will floating the barrel cause the action to "rock" forward in the stock or is the single attachment point sufficient to keep the action anchored securely?
