My poor little AR lives a hard life but it's Burris Tac 30 scope with ballistic plex reticle has given very good service over the last 6 years without ever loosing zero. To answer A.F.Medic's question, South Carolina for one. Here as long as it's CF it's legal, semi, bolt, lever whatever. Several guys I know go after deer and hogs with a 204 Ruger. I've killed at least a couple hundred myself with a .30 carbine, in fact the second largest deer ever killed in the county I reside in was taken with an M2 carbine a relative smuggled home from Korea.
