RE: Deer Slug Gun: 20 Ga. vs. 12 Ga. ??
IMO, the 12ga just packs a much better punch. Still has more energy out to 100 yards than the 20ga. And at 100 yards, sometimes that where the slug power starts degrading quick. I use the sluggun more than the rifle in MD, and IMO, the 12ga slug still does not do the damage as a 30-06 or 308.
