There is a thread where someone has just bought a Marlin.45-70 and wants to shoot 405grs @ 2000 ft/min.
I know these guns are a lot stronger than the old trapdoors, but they are not the strongest .45-70s available today.
How much can they take? Does anyone know of one of these guns being damaged due to excessive pressures? What kind of damage occurs? Are the ones from the 80s the same as the ones manufacturered today?
Thanks
