Just a little input from a shooter of 35 yrs. who has shot skeet, trap, sporting clays and numerous other games. I've tried aHydra-Coil (J & S Air Cushion), Kolar-Coil, 1 oz. 12 ga. shells, reducers, and just about everything else to reduce recoil. I am now shooting a Precision Fit Stock on my K-80 which allows me to shoot 3+ dram 12 ga. ammo and it's like shooting a 28 ga. The stock is totally adjustable up, down, cast on, cast off, short, long, firm, or soft. Check it out at
www.precisionfitstocks.com. It also comes with a lifetime guarantee. Hope this gives you some more info to answer your question.--GB
