Bigbulls is correct. Two seasons ago I went to CO m/l hunting. Took a nice 5x5 with 110 gr 777, 2f powder,and a 348 gr Aerotip Powerbelt. Worked him for 45 minutes before he showed. One shot at about 85 yards and he side stepped twice and tipped over.

Again, no scope, no powder pellets, 50 cal, no sabots. (Power belts fit the bill nicely)

ENJOY!!!
