For that repair, I would start by grinding out much of the epoxy bedding. Then carefully inspect for cracks, especially in the rear action screw area where I would expect to find a similar delamination along the same seam. Drill down the crack in one or two places with a #40 drill and using a thin epoxy inject with a glue syringe into the cracked area. Clamp and wipe off excess epoxy squeeze.

Epoxy bed the action, then drill and epoxy bed the pillars. If using a pillar identical to the stock Savage steel pillar, I counterbore the hole slightly deep and use the epoxy bedding to achieve a perfect fit.

If during the repair it becomes obvious that there is more cracking or delaminations, cross bolting or cross pinning with a hardwood dowel may be the only way to save the stock.

Good luck and let us know how it turned out.
