I may have to back pedal here. I wonder if the 336 will handle this? Isn't the 444 sized 1895 needed to make this possible. Please correct me if I'm wrong? Be Well. Rusty
The 444 Marlin is a 336 action. The only discernable difference between the 1895 and 336 is the enlarged ejection port to accommodate the 45-70 brass.
