New issue with my CMP 853

I just found a potentially fatal flaw with my 853’s barrel- there's an area of the rifling that is damaged. I found this after closely inspecting several pellets I retrieved after being shot into soft wadding so as to not damage them. The pellets are all exactly the same, having the rifling engraved perfectly into the heads and skirts for ~80% of their diameters, but the remainder shows a wide ‘gouge’ instead of the distinct, narrow rifling that these barrels have. My bore scope is too large to fit into a .177 barrel; .22 is the low limit. So I have to go by what I can see or feel. There’s nothing obvious to be seen at the breech or muzzle. When I push a pellet through from the muzzle, it goes through the choke restriction first and this makes feeling anything beyond that hard to read- that is until about 1/2 inch from where the rifling begins at the breech (remember this is pushing a pellet backwards through the barrel). There, the pellet hits a heck of a restriction of some sort. Maybe it's a chunk of debris or lead embedded into the rifling, or some other repairable problem but in any event I’ll need to disassemble it again to try to get a better look at the problem area. This could be the cause of the deformation I'm seeing and I hope it is, but they way things have gone so far with this gun, I'm not holding my breath!!
Still, I can't help but to be bummed. I have put a LOT of time and effort (and a pretty good chunk of change even at Daisy's good parts prices) into this gun in an effort to correct the low’ish MV and way too high ES it’s displayed since day one. At least now maybe I can stop looking for a reason.
I sent an email to the CMP with a request to exchange barrels or barreled actions, or the entire gun- although shipping just a barrel would be easiest for me. No idea what their response will be. If they can’t help, I do still have options even if the barrel is beyond repairing. Here are a few:
1. Replace the barreled action with a new one from Daisy for $65.00 plus shipping. Then I would basically have a new rifle, as everything else except the barrel band and receiver cover has already been replaced!
2. Replace the BA with one for a 953 and make it into a repeater (I already have the breech cover and bolt plus pellet clips). Would lose the LW barrel, but the cost is just $30.00. Would still make for an expensive 953, though.
3. Live with it.
4. Sell it w/full disclosure.

what if we removed all the warning labels, and let nature take it's course?

I'll bet that there's a burr on the transfer port.

Good suggestion, guys. I'll look at that first. I just hope the area that looks like there's missing rifling isn't really missing. The area I'm talking about is to the right of the flat spot in the smaller photo.
