Yes, please do post ultra close up pics of the brl flats and watertable, or e-mail by jpg attachment to revdoc2@cox.net The original hang tag attached to your gun described 20g LCs as tested with 7/8 oz. shot at 1155 fps. No doubt recoil is significantly higher with your 1400 fps loads-not good for the head of the stock. You might try 3/4 oz./21 gram at 1200 if available.
