The Savage Predator would be a good choice for your .243 and from what I've read about the guns, they are shooting extremely well with that stout 22" barrel.
Remington also has similar gun in the Model Seven series. It's a 20" fluted magnum contour (a bit heavier than the regular contour of the Remington 700 barrel, but not as thick as the Savage).
Like you, I could care less about the camo dipped finishes on both of these. I think that both are close to perfect for predator hunting though.
As for your friends, are they experienced hunters, or do that just do it once in a while? I think that for hog hunting with someone who's not used to doing it, I'd get a bolt action for them, instead of a single shot. Hogs can hurt you when if you piss them off with a bad shot, so having a couple of back-up shots readily available may be a good idea. If they flubb the shot and haven't had much practice reloading a single on the fly, it might be ugly.
If you shop the net a bit, you can get a Mossberg ATR or a Stevens 200 for just a little more (I've seen them for the same $$ or less as well) than a new Handi.
