Bought a carbine in '88 with a 21" .30-30 barrel. Put on a Williams peep and shot a lot of cast bullets. It has proven to be M.O.A. capable when I get things right. Soon after I bought a 21" 7 TCU barrel for it and again mounted a peep and shot a lot of cast bullets. Maybe not quite as accurate as the .30-30 but I never spent as much time on load development. Had a few real small groups with 110 gr TNT's. Then bought a 21" .22 Hornet barrel and mounted a Leupold 4X. I didn't do as well with .22 cast bullets but jacketed bullets will stay under an inch at 100, I've seen groups as small as 5/8". In all I'm real happy with they way they all shoot. Sorry no pictures, can't figure it out.
