Clearly, even though it is inferior as a Bambi caliber to many other calibers, the 30-30 has fans. I am not one of them. Looking on my hands and knees for little specks of blood on leaves as the sun goes down and the cold and sleet moves in is not my idea of a good time, but the 30-30 produced exactly that, time after time in my experience before I removed that caliber from my inventories. Assuming an adjustable rear peep sight as previously described, factory .45 Colt ammo will give you and your spouse as much plinking fun as you could want. When things get more serious, either think Corbon, or do some reloading. Use Elmer Keith's .45 loads from "Sixguns" as your guide. You should drop the lead SWC bullet as it causes feeding problems in many leverguns. Instead I think you will find the Hornady XTPs to be the cat's meow with 2400 in a Win 94A. Recoil is very mild but the load drops Bambi with no fuss out to 150 or so easily.
From 150 to 300 it is still way higher on the Taylor cartridge efficiency scale than the old thuddy-thuddy. Do what is desired. Good luck.
