Model 1895M in 450 Marlin Working together, Marlin and Hornady Manufacturing have developed a potent 45 caliber belted cartridge that is an upgrade on the classic 45/70 Government. It's the most powerful cartridge ever offered in a Marlin lever action rifle. We've harnessed all this power into a compact 7 lb. package. Like the Model 1895G Guide Gun, this Marlin lever action features an 18.5" Ballard-type cut rifled barrel, a 4-shot tubular magazine, and a straight-grip American black walnut stock with ventilated recoil pad and swivel studs.
