Jim, without knowing how bad a break it is, could I suggest that you could maybe epoxy the broken stock parts back together & then drill a 3/8" hole thru the wrist area, from inside the inletting thru the centre of the wrist area toward the centre of the butt pad. You will probably need to use a spade type drill bit to get enough length. Try to get a couple of inches past the break., then epoxy a length of 3/8" threaded steel rod into this hole. Use plenty of epoxy so it oozes out of the hole & then you'll know you've got good contact with the stock. Obviously the rod will need to be just shorter than the depth of the hole. You will then need to reshape & reinlet the rear of the inletting to your action. This is a modification that is often seen as being recommended, along with cross bolting, to prevent just this sort of stock damage in heavy recoilers. This might at least get you shooting again & at best might be able to be a permanent fix depending on the original break.
