Excellent movie based on a true story, starring Steve McQueen as Tom Horn, one of the last remaining Indian scouts trying to deal with a West that is becoming rapidly civilized.
Favorite iron in this movie is his 1876 'Centennial' Winchester in .45-60 BP cartridge. Just watched this again last night and that gun is so badass, it makes me wanna run right out and buy one. OK, so it's not a Colt, but it's in the era where the Colt still reigned supreme. Well worth the time to watch this 'un.
