I just bought a new Marlin 44 MAG 1894 20 inch barrel from Buds and it is the most accurate gun I have ever shot offhand. I can almost touch three shots with a 23.3 g H110 + 240 XTP load at 50 yards and ragged hole rested. I am pleased and impressed.
Have found an ok cast load(255 RanchDog from Range scrap and 9 grains unique) for it, but I am not done testing. Does about 2-2.5 rested at 50 yards. This is with a Skinner peep, standard aperture all else stock.
