I asked about this to the DGIF 2 yrs ago for muzzleloader season. I was told then I couldn't, but my county (in the sticks) is a non rifle county for some reason (love how henrico is ok though and its mostly city)
Can always call and ask them. I have called 4 or 5 times in the past couple of yrs and they are always helpful. They have a couple gray areas in the book so I call and confirm things.
Wonder how long muzzleloaders will continue to go myself. Buddy sights his in out to 300 yards.
I just use a sidelock I built a couple yrs ago mostly now. Still never took a deer over 50 yards. Not even with my .45 cal that has a scope on it.
