    I have only messed with that stock a little but if the action screw spacing is the same it should fit pretty easily. Might need the magwell opened some.

    i was really concidering the 7mm tejas (7mm ultra mag with 50 degree shoulders) brad stair's rifle has 2500 rounds down the tube and still shooting great. its about 300 fps faster than the ultra mag. with that speed i'll shoot the 200 gr wildcat.gun)
