In the hollywood flick and remake of Monte Walsh, Tom Selleck uses an 1886 Carbine which was chambered in 50-110 when he goes after Shorty.
According to a website
www.imfdb.org the only movies that have been filmed using the 1876 are as follow:
Crossfire Trail, Tom Selleck as Rafe Covington and Virginia Madsen as Anne Rodney..2001
Tom Horn, Steve McQueen as Tom Horn.... 1980
Tombstone, Michael Biehn as Johnny Ringo and Jason Priestley as Breckinridge, Michael Rooker as Sherm McMasters and Peter Sherayko as Texas Jack Vermillion... 1993
Prior to the film Tom Horn the Winchester Model 1876 was not featured in Hollywood westerns. The Winchester Models 1873, 1892 and 1894 were the rifles that got all the attention. So sayeth...www.imfdb.org
