Been measuring my digits to numbins' and here goes.
1. I examined 19 empties + right chamber empty
No missing pieces inside nor out
The primer of the blow-out shell is similar to the others
NONE of the empties showed the extractor imprint found on the blow out shell
2. The entrance to both chambers measured .818". Hunter Arms specs is .809" so it's possible the chambers could have been hones slightly?
3. The piece wall thickness
The section which is the forcing cone (superiorly) was .123"
3/16" past the end of the forcing cone was .105"
The MWT was .094"
4. Around the edges of the blow out
5/8" from the breech at the apex of the blow out .150"
At the bottom 1 1/8" from the breech .130"
Moving along the bottom and the front was uniformly .121" to .123"
At the top, 2 5/8" from the breech .119"
The thinnest section was at what I believe to represent the apex of the bulge from 2 1/2-2 1/4" from the breech and was .110"
1 1/4" from the breech .122"
1 1/8" from the breech .126"
My assessment is that even with the likely elastic deformation with the bulge, all wall thicknesses are adequate.
