I'd look to the '86 or '92 for the following reasons:
1876 vs
1886: The 1876 version used the same toggle like setup as the 1873 and
so it's limited to less powerful calibers and loads than the 1886. The
originals were produced in a wide variety of calibers including 33 WCF,
38-56, 38-70, 40-65, 40-70, 40-82, 45-70, 45-90, and 50-110, a great
opportunity if you're a reloader. Advantage 1886.
1892 vs 1894: The main
attraction I see of the '92 over the '94 is that the '92's shorter
action gives you the opportunity to shoot some great handloading
specialty calibers such as 218 Bee, 25-20, 32-20, 38-40, and my pick,
the 44-40. The '94 is great in 30-30 or 35 Win but then it's just a Win
'94 and everyone should own a 30-30. As a handloader, I'd really like
the 44-40 caliber in a rifle. Advantage 1892.
