The action screws need to have plenty of room and should not touch the sides of the holes in the stock, if it were me, I would pillar bed it as well, it gives a much stiffer bedding platform. Brownell's sells pre-made aluminium pillars with instructions.
How much material did you remove to make room for the epoxy? The chips may be from there not being enough depth in the epoxy.
How tight is your recoil lug? Tight fitting lugs have a tendency to chip the bedding material as you disassemble the rifle.
Is there room behind the tang in the stock? The tang needs clearance at the rear in the stock, the bedding compound should be under but not behind the tang on anything bigger than a 270.
Your pics were a bit blurry, so the detail wasn't great.
It looks OK, but how does it shoot?
