My current thought is a Henry Single Shot rifle in 3030 win, rebored to 460 S&W. That chambering would provide plenty of power. Like 45-70 type of power, and light to heavy bullet options along with a 200 yard capability. It would meet both Maryland and Delaware regulations. I have a Weaver K4, just waiting to ride on top of that rifle. Decisions, decisions......
another neat thing about a 460 SW is you can use 45 long colts and 454 Casull cartridges in your 460 SW.
