I have a PSE Tac 15i crossbow coming soon. It slings an arrow at 402 fps with incredible accuracy. I am thinking of this as an ideal western state mule deer hunting tool. Especially for Spot and Stalk. Tac 15 video It takes a while for the video to load. PSE Tac 15 Spec Sheet But I have zero experience in mule deer with archery equipment. So tell me how to Spot & Stalk mule deer. I'll be hunting up on the top of the Big Horns in NW Wyoming this fall. 8,000 feet or so of elevation.
