I have both the 444 and 45/70. My 444 works really well. The 45/70 had something wrong with the chamber and is getting replaced or corrected. It would not fit some of the factory loaded ammo in the chamber correctly and it split a few Winchester factory loads right down the side of the brass. Both barrels are loud.
My 45/70 24" SS works well though with the factory loads, and handloads.
