I have the same model as Ridge Runner and its a heck of a gun. For a hunting situation heavy barrel or no is really just preference. Its not a FACT that heavier barrels shoot better. You're going to shoot well with something you like. Savage and Marlin both make excellent bolt action rifles in the 17. The slight advantage is going to have to be given to the savage in my OPINION because of the accu-trigger system.
For squirrels and other small game the 17 is pretty much perfect. As for yotes, I personally prefer a larger rifle for them but if you must them I would make it a head shot.
