Muzzleloader regulations have been updated in the state of Colorado. It has been determined that a minimum of .50 caliber is required for hunting elk and moose with a conical projectile and .54 caliber when hunting with a round ball projectile. The following info was provided by the lead wildlife investigator Bob Thompson from Colorado Parks and Wildlife as well as the CPW Wildlife Regulations page:
