I have a 243 early 50’s original stock. It has a small crack opening at wrist. Doesn’t make since 243 does not recoil that much. Took it out of stock and it has about an 1/8” of movement forward and backward. I am going to get crack repaired. My question should I just put some epoxy under the recoil lug since I have to get crack repaired anyway or should I put some kind of removeable plastic or metal shim so it can be removed??
