I have a TC Hawken percussion on its way to me as my first muzzleloader to fool with. If I can successfully climb the learning curve in the next 4 or 5 months, I will try for a tag for deer or elk here in Colorado next year. Deer seems pretty straight forward: anything from a round ball on up, so long as you have enough powder involved and good accuracy. Elk are another story. I would e limiting myself to cows under 100 yards, given my eyesight and my lack of interest in dealing with an 800 pound carcass. If cows are on the menu, what is a feasible conical to consider given a 28 inch barrel and a 1 in 48 twist? Would a 320 REAL suffice?
