The '76 is basically an elongated version of the '73...Winchester's attempt to compete with Sharps on the Buffalo prairies. It was more successful with normal hunters than market types. The '86 was all the '76 tried to be but a day late and a dollar short for the big shaggies that were pretty much shot out by the time it hit the west. The 1881 Marlin in 45-70 is a fine weapon, but a bit late for the Buffs also.
