You could go with an English sporting rifle or a long barrel Jaeger with such a barrel. I presently hunt with a fullstock circa. 1790 62 cal. English sporting rifle that uses this barrel. I have made half stock English sporting rifles by cutting the barrel back to 32" thus making it a tapered barrel. You have to cut the barrel from the muzzle to do this. I know some O/C people have an objection about cutting the muzzle of a barrel, but it is no problem and recrowning is not difficult. You have a lot of possibilities with such a barrel.
