Something you can do if your rifle has a hollow plastic stock is to take off the butt pad and put a pound or so of lead shot in the cavity, then pack some plastic shopping bags or foam in behind it to keep it from rattling around before putting the butt pad back on. This will increase the weight of the rifle and decrease recoil by quite a bit. I ended up doing this with my Remington 700 SPS .30-06 and it worked quite well. It also balanced out the rifle; plastic stocked guns can be front-end heavy, especially if they have a longer 24" barrel.
Fill the cavity completely with shot and it will shoot like a .243. Only problem is the gun will weigh around 10-12 pounds and be extremely unbalanced.
