You can't go wrong with a Ruger 10/22. In production over 50 years and plenty of accessories to trick it out any way you like. Just try finding .22RF ammo... I was looking at getting a carbine in .45 Long Colt. A used Rossi Circuit Judge or a new Rossi M92 Puma lever-action. While the Circuit Judge will process .45LC, plus .410 slug and shot shells--it holds only 5 rounds and all 5 must be reloaded by swinging the cylinder out of battery. The M92 handles .45LC ammo only, which includes shotshells. The advantage over the Circuit Judge is the tubular magazine can be topped off through the loading gate with the action closed and a round in the chamber. Plus the M92 may be effectively operated by right- and left-handed persons. The price of the lever gun stalls me though. After two years, that gun is still on the rack.
