A pistol scope would have to be mounted "scout" style due to the extended eye relief...
If there is a 2-12, I would consider it good as close in shots are possible. Folks who are able to bag a hog on a stalk style gun hunt are severely outnumbered by those who never see a pig. This said, chances are better at a long distance shot than pounding the swamps in hopes of shooting one at 25-50 paces.
bswiv may be of help as will a few others on here. I personally see a few in and around crop fields but have seen only a hand full of shooters while out without the dogs rustling them up. Their nose is a ton better than a deer and their hearing ain't far behind their nose in ability to bust you hard.
