Whatever bullet select you make, you need to get to the range and practice with your muzzleloader well in advance of your hunt. Get a friend that knows a thing or two about muzzleloaders to go to the range with you to give you some pointers. The more lead you sling downrange will increase your odds of making a successful hunt.
Good luck and if you have more questions, let us know.
