we have just started having a bad hog problem in the last few years, and its true what the others say. you can't shoot those little ****s fast enough to cut down on the population. if i'm not mistaken a sow can have up to three litters a year and can have up to twelve pigs in a litter. thats 36 pigs per year per sow. ofcourse thats a tad extreme but you get the idea. we somewhat control the population by shooting every one we see, and by trapping. in fact i killed a boar this evening deer hunting.
