While living off grid in the Talkeetna Mts in Alaska in 1972, I bought the very first M95 Marlin in the state. There was no data for modern loads, so I started with the max load in the old Lyman reloading book and worked up in 1 grain increments using IMR 3031. 52.0, 53.0, 54.0, 55.0, and finally 56.0 grains. All fired cases (Winchester) fell out of the gun when ejected with no resistance and no pressure signs in the primers whatsoever. HOWEVER, the recoil with the crescent butt plate was more than I could stand! I then searched for the most accurate load, which was 54.0 grains and shot that load, exclusively, with the 405 Remington bullet and Fed 210's, from the winter of 1972 till I left Alaska in 1979. It killed moose, caribou, bears, and any other miscellaneous critter that came into my crosshairs as if hit by double-forked lightning. None of the bullets "dropped them" (except head shots, of course) but they never staggered more than 15 or 20 yards. There are more efficient powders out there nowadays, but 3031 is still available. VV133 is it's equal in accuracy and velocity, too.
