Many good heads on the market-shot placement of course. I started shooting Rocky Mountain 3 Blades when they came on the market in the 70s. Buffalo, Whitetail, Elk, Caribou, Black Bears, Mule Deer, Wild Hogs, Rams, Goats & a few others have fallen to them. No need to change after this many years. Excellent Blood Trails-fortunatly, all have been short.
Son & Brother have also used them for many years.
