RE: synthetic stocks
In addition to the excellent suggestion of using your sinkers with foam insulation,I'd DEFINITELY get a sims limbsaver recoil pad. Another thing which will reduce recoil is lighter weight bullet loads such as 150 gr bullets instead of 180s. Both remington and federal offer reduced recoil loadings for your rifle and are plenty deadly at ranges within 200 yards-they will reduce recoil by about 1/2-about like a .243.
