Good point. I will contact the FLFWC and find out exactly what are the requirements. Especially what type of equipment can be used? Sights, primer system, in-line etc. never even considered the powder type an issue; good to know. Im looking to either build or purchase depending on mood at the moment, an accurate hard hitting muzzleloader that will be able to take down a 900 pound critter. Would like the lean up and fouling be at a minimum. The area where the hunting will be is an large island surrounded by a shallow bay, tidal swamps, and marshes, so its looking towards some from or stainless or corrosion protection.
