RE: Deer Slug Gun: 20 Ga. vs. 12 Ga. ??
Before the advent of rifled slug barrels and sabot type "slugs" (which are nothing but big bullets), the12-Ga. had a decided advantage for shooting deer and bigger game. Using a sabotted bullet, this is no longer true-the"20 is plenty". In addition, you can get the 20 in a lighter platform.
