BRPC and Big John: I agree with Big John, but I will also advise you that you will probably gain both velocity and uniformity of velocity, which makes for smaller groups, and a higher amount of recoil. With the wads over the powder, you should be able to back that 100 gr load down to 80, or even 70 grains, and save your shoulder, while getting better accuracy. Borrow a chronograph and check it out. The wads do seal the bore, increase velocity, and give uniformity( Standard Deviation of Velocity in modern technospeak) of velocity for smaller groups.
