I used a marlin 45/70 for several decades, it was and is an excellent choice,
I used mostly 350-400 grain hard cast gas check bullets and RL7 or IMR 4198 or IMR 3031 powders and,
all were capable of 2" or less 3 shot groups at 100 yards off a good bench rest, with a 4x scope.
about 20 years back I swapped to a browning BLR in 450 marlin,
personally I don,t regret the swap and yes the browning IS a marginally more accurate rifle in my experience,
but theres nothing youll hunt with either rifle or caliber that will know the difference.
if you prefer the marlin,or the BLR youll be well armed, especially if hand load and use the 350-405 grain bullets,
either jacketed or hard cast
if I buy a new marlin 45/70 it will be the cowboy version
