You've been watching way to many Primos videos. Calling during bow season can be done, but must be minimal at best. During rifle season, forget it! Not in Colorado where there are 5 other hunters within earshot. Elk are already on def-con 5 alert during gun seasons, any call at all says, "hello elk, there's a human right over here." During rifle seasons it's about predicting where the elk will be, calling them too you was 6 weeks prior.
