Another vote for the Buffalo Classic. I put a better rear sight on mine, and, shooting offhand, it is hell on the 200 yard plate at the gun club!
Standard 405 gr bullets will drop about anything in North America, and this gun is very easy to shoot. You do not need amped up ammo for this old Warhorse.
If you shoot a hog in the nose with the BC, he will quickly acquire another exhaust port! In other terms, you will very likely get a through-and-through regardless of the angle of your shot.
After 53 years in the Gun Culture, and countless firearms, the Buffalo Classic has become one of my all time favorites on the range. It also qualifies as a Primitive Weapon in many states.
