Savage,

It is not really a matter of what the difference is between one weapon or another. Like many other states have already done (i.e. MS), Tennessee would have to further define what a primitive weapons actaully is.

For instance, according to the state of MS, the definition of a primitive weapon includes " a rifles of an original design, replica, re-introduction or reproduction of a type produced prior to 1900." If the state of TN adopted this defintion, and the firearms you describe met this defintion, I would say you are good to go.

If the firearms meets this criteria, accuarcy and distance wouldn't necessarily matter. My point as it relates to accuracy is that a hunter has no accuracy advantage using a primitive style 45-70 as compared to modern in-line muzzleloaders.

More accurate?? What kind of muzzleloader are you shooting head over to the guns and gunsmith forum, and check out the "im gonna call it good thread". No more accurate than todays MZ
