Tanner,
Don't laugh, but I bought a Ruger American Rifle (9 twist) just to play with those bullets. 22" tube, but the mag box (on mine) measures 2.90". I've shot it with a couple other bullets and its a shooting machine. Should be fun.
We'll see how it turns out with the 105?
Heck man, I guarantee it'll stabilize the 105s, and if it does, you've got yourself the perfect truck rig. A 2.9" box does not suck at all either!
