Your cleaning may help.
Sometimes excessive headspace will show as a slightly raised primer- I don't see that in your earlier picture. Too little would "jam" the case mouth into the edge of the cut and would likely be visible, and I don't see that either.
The only reliable way to check it is to use gages.
If you give up after the next outing, and want to send the complete upper to me- I'll try it out by firing on one of my lowers and check the headspace. You can send the complete upper person to person as it is not a "firearm". No charge except return priority mail cost, which is like $7.
You have not put your city and state in your profile, you may be close enough for someone here to help in person.

Don, that is very kind of you to offer to take a look for me. I updated my profile to include my location which is Indialantic, FL; near Kennedy Space Center.
There aren't really scratches per se on the casing, just the darkened area with the line in it that you can see pretty well in the last 2 photos I posted, and the triangular shape in the one on the left towards the top. Hopefully the cleaning did some good! Thanks again for all of your help.
