The mercury recoil reducer will definitely take the bite out of the gun. I used one in my very light weight Beretta O/U 12 guage shotgun for heavy duck loads. It will add back weight to the gun. It was not really a problem with the shotgun. I would think that a heavier rifle barrel will have a somewhat better balance to the gun with the reducer in place. The recoil reducer will add about a pound to the gun. If balance becomes an issue, you could always add weight in the forend of the stock.

I have not found a need to add one to any of my rifles yet. I would prefer the recoil reducer to a muzzle brake.
