i have alot of success calling elk. i usually go out around the middle of sept and start calling. last year i called in four legal bulls in two day's in the area my buddy and i hunt. I use only reed mouth calls. but there are alot of good calls out there to use. i hunt muzzleloader for elk. so we go out early to find bulls for the muzzleloader season. My buddy and i have tagged out on elk every year for the last four years doing this. good luck
