For deer hunting, the new 20-ga. sabot-type slugs are so much better than the old Foster-type that it is no longer much of an advantage to shoot a 12 for deer. But the 12 still has a heavier shot charge, and hence more range, than the 20 will ever have. But, the 3" 20-ga. shell with 1-1/4 oz. of shot is pretty impressive, if your gun is bored right!!

Keep yore powder dry!!
