Is there a difference between model 10 and model 11 actions. My budget will allow a Trophy Hunter XP but my heart wants the Precision Carbine. Would there be a noticeable difference to the average shooter regarding accuracy, smoothness of action, etc? I believe both have the DBM. Can I get an accustock for a gun that did not come with one? Are stocks different due to barrel thickness? I'm a NOOBIE to rifles.
