Finally...someone else that owns a TC Treehawk!! It was my 1st muzzloader, and a very good one at that. For deer hunting I was shooting 275gr maxi-ballets(a conical HP) with 90gr Pyro. I also mounted a scope on my gun a 4xsimmons. I was shooting 2 inch groups at 100. I shot a 142B&c net buck last year 264lbs FIELD DRESSED, 30yards...went down hard, 20yards. Everyone laughed at my little camo gun, until they saw the deer I was shooting with it. Not many people in Ont. hunt with muzzleloaders.
