I've killed a couple of dozen deer with my .243, as well as a fair number of coyotes and prairie dogs. I'd have no qualms about doing in hogs with one.
Look around for good used reloading equipment to hold down the cost per shot, and the .243 is a good range toy as well as a superb hunting rig.
I like the 2X field of view with my 2x7 scope, and I've found that 7X is plenty of magnification for prairie dogs to 300 yards.
I've worked into some ten feet from hogs, down in the bottomland swamps along the Appalachicola River below Blountstown. I can tell you that the field of view of a Weaver K4 is nowhere near wide enough.
