My favorite 1,000 yard match rifle is my 1874 Sharps in .45-2.6" (.45-100) from C. Sharps Arms in Big Timber, Montana. The sights are from MVA, a spirit level front with interchangeable inserts and their "Soule" style rear, featuring 40 MOA of windage on a micrometer barrel and elevation on a vernier scale.
The Hadley style eyecup provides rapid aperture selection for varying light conditions:
Top rifle is the match rifle, featuring their #1 heavy octagon in a 34" length. The rifle weighs about 14 pounds (limit is 15). Shown with another 1874, this one from Shilo Sharps, also in Big Timber (right across the street, as a matter of fact). This one has a standard weight 28" half octagon with a Hartford collar at the breach end. Chambered in .45-2.4" (.45-90), it comes in at less than 10 pounds. Wonderful hunting rifle, it balances perfectly between the rear sight and the front of the action.
