I am trying to decide which lever 44 to get for deer season now that my state allows straight wall cartridges in slug counties. I like the Marlin 1894, but see that the rifling is only a 1-38" twist. The Henry Big Boy has a 1-20", as does the Ruger 77/44 if I wanted a bolt. My question is, in the event I ever wanted to shoot 300gr bullets, would the 1-38" twist in the Marlin stabilize them, or is it too slow and limited to the 240gr bullets. I do plan to shoot 240gr XTPs, but wanted the rifle to be able to shoot the heavier bullet.
