My TC Firehawk will shoot sabot or TC maxi-hunters. Hawken rifles may shoot a conical better as the barrel twist is usually 1-48" and will stabelize a conical. I'd start with 90 grains of 777 and or 3f black powder if you want to be more tradional, then go to 100 gr after you get on paper. You may find a TC maxi-hunter or a Buffalo bullet will shoot pretty well if the sabots won't group for you. In all due respect the 120 gr of black powder in a 45 cal is way over kill and might be over the max charge rating for the barrel, something to check on. I only shoot 110 gr of 2f in my 54 Hawken.
