Re: Quick skim bedding question...
I've got a B&C A5 stock that I bedded and decided to do just as you've done. The rear tang area was raised just a few hairs. It aligned the ejection port area perfectly and gave proper float amount(i like just under 1/8"). Turned out great.
Your recoil lug area looks good, the rear lug contact surface looks filled and neat. In front of the recoil lug usually receives a relief cutout to help ease future removal and installation. I'd just use a dremel/file to make it neat & uniform.
I agree on the rear tang, air trapped around the bolt hole. The area around the tang you could backfill later.
Again, you've got good bedding surface on the front receiver and lug pocket, don't alter that at all by raising the rear tang surface any higher/lower when you refill the rear tang. Your front receiver ring area and recoil lug pocket are the 2 most critical areas in stress-free bedding. Did you check the bottom of the recoil lug for clearance from the stock after? I usually give that area a light scrape with a chisel.
When refilling the rear tang void(s), think "rear-front height alignment", and don't change it. Keep some of the rear tang material there so you can squash out excess devcon using pressure/tightening the rear bolt. Torque front bolt 1rst(height alignment off front first), then "snug" the rear to squash out excess devcon. Use plenty of kiwi or other release agent on that rear bolt/threads.
I don't bed in front of the lug, I don't believe it helps/hurts bedding 1-2" in front of the lug... but that's just me.
Hope this helps
