On areas of stock with a rounded profile, I have successfully used lengths of car innertube. If you stretch the rubber strip around the mend, finally anchoring with insulation tape wrapped around the rubber, you will find that as the rubber trys to shrink back to normal size,and strong 360 degree even pressure is exerted onto the mend.

That was a tip given to me by an old gunmaker who used to repair a few broken stocks, so I guess he know what he was taking about.

Good luck with the repair
