RE: single shot rifles
My son shoots an NEF single-shot .243 to great effect. It's not a tack-driver but then that's not its purpose. I handload for it and he practices with reduced load then full power hunting. Avgs. 1 1/4-1 1/2 at 100. I've never shot it farther than that but it handles and shoots good. Oh yea, I have many nice rifles in my collection and have used many a patch to keep the barrels clean. The NEF fouls less than any rifle barrel I have ever cleaned! Great for the money.
Check out that H&R Ultra in 25/06...single-shot laminate stock, a frind of mine flat murders 'yotes and deer with his. It's pretty cheap too.
