The cowboy repeater is a lever-action rifle firing small-caliber .357 Magnum rounds. It has a peep sight similar to that of the brush gun and This Machine. Due to the gun having a tube magazine, it is reloaded by hand one bullet at a time, as such it can be interrupted mid-way through reloading and fired if needed. Because of this, it gives the gun the added advantage of being quickly available to fire again if only a single/few rounds are needed.
Its low Gunsskill requirement of 25 makes it an effective choice of weapon for a player character with only a modest investment in the Guns skill.
At later levels, the Cowboyperk makes a fully modified cowboy repeater a useful weapon, with the +25% damage bonus from the Cowboy perk, combined with the common .357 ammunition and ease of repair, makes it a good all-purpose weapon.
The firing animation incorrectly depicts a bottleneck cartridge case even though .357 Magnum and .38 Special are straight-walled cartridges.

pcps3xbox360 This is one of the weapons affected by the round-by-round reloading bug. Sometimes all other actions will be locked out after reloading until the player attempts to fire the weapon. The attempt will have no result aside from unlocking the ability of the player to take actions. The player will still be able to move but will not be able to take any actions which are unavailable while reloading. If this bug occurs during a V.A.T.S. reload, it may make it so that the player must reload an earlier save. [verified]
