I recently got a Thompson Center Grey Hawk .54 caliber muzzle loader in a trade, and know nothing about it. So I was wondering if anyone knows what twist it has, and what type of loads would be best to shoot in it. I'm brand new to muzzle loading, so any help would be appreciated. Also, which would be better to shoot in the gun: conicals or round balls? I'm hoping to do some hunting this fall with it for deer and elk. Thanks!
