The recoil reducer does work. I have a 26 in barrel nova and installed the reducer last spring. I shoot mostly trap, and have used everything from the cheap 1oz promo loads to 1300 fps sporting clay shells. The mercury reducer does take the kick out. My shoulder used to be black and blue the next day after 125 rounds, now its fine. It also balances the gun better. What you wind up with is a very accurate, reliable trap gun that will shoot any shells you would like to try. You can also remove the hard rubber recoil pad that the nova comes with, and replace it with an aftermarket one that will soak up whatever recoil is left. The PAST recoil pad ,which you wear like a shoulder holster, will also absorb lots of recoil. Good luck and I hope you find the solution that keeps you shooting.
