I live on the shotgun only side of VA and have killed the majority of my deer with buckshot. Im a big fan of 3” federal premium OOO copper plated out of a mossberg 835 with a modified choke. Also killed quite a few with 2 3/4 and 3” OO. Main thing is to pattern your gun and don’t get greedy with your range. Buckshot hits like a hammer at closer range but from my experience it doesnt leave good blood trails.
