Ted, your effort and willingness to admit that recoil is an issue are refreshing. I've seen skeet and dove shooters who brag about not having recoil or flinch affect them but almost topple over, bracing for recoil, on a FTF from faulty ammo or failure to have one in the chamber. There is a "sticky" over at shotgunworld in the reloading section regarding 3/4 oz. in the 20 ga. I know you have opinions regarding reloading, but it may be worth your time. You might even have a 25 lb. bag of #9 lying around.

Your son's work at the range would be a good source of the best hulls for the task. 20 ga. promo loads are relatively cheap, but it is still cost effective to reload specialty rounds in the 20. Keep going forward. Gil
