I shoot a T/C renagade 54 caliber using open (peep) sight and pyrodex powder. Most of my hunting is in Colorado, but I also use it in Texas for whitetails (where scopes are legal) and I use the same rig (no scope). Max range for me is 100 yards. In my hands it IS a primative weapon.

I don' t think inlines are that big of an advantage as long as you don' t allow scopes. In the hands of a few perhaps, but not many.
