What is cheaper 12 ga or 20 ga shotgun shells?
About the same price. 12ga Promo loads can usually be found slightly cheaper at the Big Mart stores. Either one is fine for skeet. You can shoot light loads out of a 12ga so the recoil will not cause fatigue after a lot of rounds. Even though you can shoot a lighter load of shot out of a 20ga, the shotgun will usually be lighter, so the recoil will be about equal. Go with what you like. A 20 gauge will be more slim than a 12 ga so you might like the lines of the gun better. As for shell use a light target load with #9 shot for skeet. If you shoot trap, use #8 as the clays will be farther away, and the larger pellets will have more momentum at long range.
