An article with pictures appeared many years ago in a Gun Digest, suggesting the recoil lug area of the stock being hogged out side to side - front 2/3rds and a rough square steel 'plug' be glassed into that spot with Devcon Plastic steel. I used this method for years, even on a soft wood (F. Reinhart Claro) stocked .458, but that stock let me down periodically, by cracking, until I put in crossbolts. The wood had huge grain pores and was very soft. The .375's I'd done previously to this and the later .458 Alaskan were all just fine with the plate in the recoil lug area and actions properly glassed in Devcon. It was the 50/50 mix that I'd used, which is no longer available. JB Weld seems to do OK of me nowadays.
