R7,
Without installing a brake on the barrel, you can either add weight, or reduce your loads to reduce recoil. I assume that reducing the loads would not be your choice, nor would it be mine.
Mercury reducers do add weight. I am told that they are effective, but so is anything added into the stock that increases it's weight by 8 to 16 ounces, which is what most reducers weigh.
I would caution you that reducers add their weight in total to the butt of your rifle, and can cause an unbalanced feel. This might not bother you, but it is a consideration. The judicious addition of weight distributed in the forearm, wrist, and butt will give you a heavier, but balanced stock, that will be much handier to shoulder, and swing.
A little drilling can open up some relief areas that can be filled with lead, then glass bedded into place. With this technique, you can add a bit at a time until you feel that it is just right.
Best of luck with your rifle!
