I recommend a quality M-14 clone in .308.
A goodly percentage of the time when hunting hogs you won't see anything.
When you see any, you're likely to see 30 or 40 of them at once.
A full power rifle with good handling and a high capacity magazine will allow you to make the most of those opportunities.
I have friends that do well with SKS's or AR-15's, but the .308 caliber, combined with a high quality bullet (I prefer Nosler Partition Golds) will allow you to blow a hole from rectum to brain at any reasonable range.
As far as scopes, the sky is the limit. If I could afford it, I'd hunt with a day/night capable ATN or Varo. Since I can't afford them, I usually use a Leupold VXIII 1.5x5.
Don't spend extra money for more magnification, a four power scope is plenty for hogs even at 400 yards.
A lighted reticle can be useful, but don't buy a cheap scope that's so equipped thinking that it'll give you an edge. Put the money into good quality glass, then, if you can afford it, tack on the features.
