There were 2,361 cartridges, cases and bullets recovered from the entire battlefield, which reportedly came from 45 different firearms types (including the Army Springfields and Colts, of course) and represented at least 371 individual guns. The evidence indicated that the Indians used Sharps, Smith & Wessons, Evans, Henrys, Winchesters, Remingtons, Ballards, Maynards, Starrs, Spencers, Enfields and Forehand & Wadworths, as well as Colts and Springfields of other calibers. There was evidence of 69 individual Army Springfields on Custer’s Field (the square-mile section where Custer’s five companies died), but there was also evidence of 62 Indian .44-caliber Henry repeaters and 27 Sharps .50-caliber weapons. In all, on Custer’s Field there was evidence of at least 134 Indian firearms versus 81 for the soldiers. It appears that the Army was outgunned as well as outnumbered.
Survivors of the remaining seven companies of the 7th Cavalry asserted that the Indians were equipped with repeating rifles and mentioned Winchesters as often as not. Major Marcus Reno claimed: ‘The Indians had Winchester rifles and the column made a large target for them and they were pumping bullets into it.’ Although some white survivors claimed to be heavily outgunned, Private Charles Windolph of Company H was probably closest to the truth when he estimated that half the warriors carried bows and arrows, one-quarter of them carried a variety of old muzzleloaders and single-shot rifles, and one-quarter carried modern repeaters.

The firearms analyses has verified 47 different types of guns used by the warriors. A forty-eighth weapon is represented by metal arrowheads, showing that the stereotypical bow and arrow was also used. By using modern crime laboratory firearms identification techniques it was possible to discover that a minimum number of 415 guns were used by the Indians.
This is a conservative estimate as groups of round balls, on which these techniques are not as effective, were counted as one gun per caliber.
Indian arms included the .44 caliber Henry, .44 caliber Model 1866 Winchester, and the .44/.40 caliber Model 1873 Winchester, all repeating rifles. The army in 1876 did not issue repeating rifles
The army's single shot Springfield was simply not as fast as the repeating rifles, although it was more powerful and more accurate than the majority of the Indian arms. Indian arms also included the army's Springfield carbine and Colt revolver. These arms could have been captured either in the Rosebud fight or the valley fight against Reno and, in addition, some were no doubt taken from Custer's men during the battle. Antiquated muzzle loading firearms were also well represented.
