I dedicated a week targeting lions right after new year's. Never did call one in but it wasn't for a lack of trying. Mostly blind calling since there was minimal snow at the time
It was cool except it was almost dark. Then after hiking back toward the truck several hundred yards away from where I first saw it , it reappeared slinking around a rock still watching and following me. Didn't feel very cool anymore
I have no personal experience but I do know that Jon Collin’s with the FoxPro podcast did an episode with Stacey Morris about calling in lions that I found very intriguing!
