ok if you had never shot a muzzleloader before and planed to buy either a muzzleloader or sluggun in may or june and would have 4 months to get to know the muzzleloader and had a mossberg 500 smoothbore

and could use the sluggun from nov 17th to dec second or the muzzleloader from nov 17thto dec 23 which is 3 more weeks
would you buy a muzzleloader or a slug gun
also what are the pros and cons to each and dmax yardages of each
