Watcha gotta do is to get an 1100, add a magazine extension, and load it to the gills with trap loads. Then, go to town on 'em. Trap loads will do the trick, if you're close enough. Keep it topped off, though, in case you run into bunches of 'em.
You can roll a turd in peanuts, dip it in chocolate, and it still ain't no damn Baby Ruth.
