Colorado Wildlife Commission
Outlaws Inlines for Primitive Weapons Season
In action Thursday, January 15, 1998 the Colorado Wildlife Commission approved regulation changes restricting the types of firearms allowed during the autumn black powder hunt, and changed the season's official title to "Primitive Muzzle Loading Season Only." Effective Mar. 1, 1998, hunters will no longer be able to use rifles with in-line ignitions systems to hunt big-game during the special muzzle-loading season. Only muzzle-loading rifles "having an exposed external hammer such as a flintlock, percussion cap sidelock or underhammer" will be allowed.
The ignition system of in-line muzzle loaders has a firing pin directly in line with the explosive charge of black powder in the rifle's barrel. More classical sidelock muzzle loaders have an exposed ignition system -- usually located on the side of the rifle -- with a longer, less direct route to the explosive charge. Both types were previously legal. The regulation change was drafted by the Colorado State Muzzle Loading Association in response to concerns about the improved performance of newer in-line models, which the association said detracted from the "primitive" nature of the special muzzle-loading season.
The Commission approved the association's proposal with minor modifications that change the regulation's wording but not its substance. Although in-line muzzle loaders will be prohibited during black powder season, they remain legal for regular big game seasons.
