Pepper, here in ID min. cal. for elk is 50. Not for sure, but I believe other states have similar restrictions....... Something to think about before buying a new muzzleloader. I have always shot a traditional style Thompson Center hawken in 50 cal. I have hunted with sabots, lead conicals ,and round balls, depending on the restrictions in the area I'm hunting. I have taken several mule deer, elk, and antelope and was always impressed with the 50 cal. Some prefer modern in-lines and thats fine too. I have run into other hunters in the field that could not belive I would use a traditional muzzleloader when in-lines are legal, again, personal preferance. I you have the chance, shoot both and go with what you feel most comfortable with.
