thanks for the help. the circle indentation is from the set screw for the cross bolt safety. not sure about the lower portion. i'll pull the stock again and check it out. perhaps i'll try bedding the ends.
I suspect that the stock is resting on the set screw and too much of the recoil force is being transmitted to that one tiny spot, hence the crack near it. I'd relieve the stock at the circular dent by drilling the dent slighty larger and deeper and then bed the rest.
