I bought my dad .410 inserts for his Beretta EL. It feels like a .22. He also shoots a Daly 20 ga O/U hes been shooting for decades. Even with shoulder problems, no problem. For rifle shooting, he uses my Rock River AR with a scope from the bench. All work well for him. At 80, he can still run 25 at skeet or trap. He recently used his LC Smith Field Grade to break 25 at trap. Pretty cool:)
