Have all rounds from the 50 box in question that you have already tried failed to fire? If so try seating the primer on a couple again (try seating deeper) and try those. If for some reason that box didn't seat all the way it can cause exactly what you are experiencing.
"And you shall know the truth, and the truth shall make you free.” John 8:32 (New King James Version)
The Dunning-Kruger effect is alive and well.
Forget the tape, all you need is a spent fired primer and resized case.
Measure the length of the resized case and write it down.
Next take a spent primer and with just finger pressure start the primer into the primer pocket.
Now take this case and slowly chamber the case and let the bolt face seat the primer.
Now take the case out and remeasure the case and write it down.
Then subtract the first case measurement from the second.
The amount the primer is sticking out from the base of the case is your head clearance.
If you really liked this posting please send cash or checks to bigedp51's cheap bastards headspace gauge PO Box 17112
This money will be used to stop the importation of cheap Chinese scotch tape and lower the national dept. (yes we recycle used primers)
ROTFLMAO, (about your "cheap bastards headspace gage" of course).
Nice pics and graphics, ED!
LOL. Count me in!This money will be used to stop the importation of cheap Chinese scotch tape and lower the national dept. (yes we recycle used primers)
Hahahaha big Ed thanks. I'll give it go and let you guys know. Problem I have I recently invested in Chinese scotch tape and you are killing my gun funds endeavour!

The photos were .303 British cases I made up for use in Enfield forums and checking actual headspace. When you the add case length difference to your rim thickness you have your actual headspace.
A .303 British Enfield at maximum military headspace of .074 and a case with a rim thickness of .058 could have .016 head clearance. Thats .014 more than .002 shoulder bump!!!!!
You can also use this primer method with a Hornady case gauge to get your chamber headspace length and compare it to a fired case. (brass spring back)
Didn't make it back in time to use your method Big Ed. I'm at work now, but I got time tomorrow after I wake up. Pitbull I don't have my load sheet in front of me, but I think it was around .003" bump with the socket. I'll verify when I go out there to measure with Big Ed's meathod. A 9mm case isn't a bad Idea. I got the socket idea off here a while back and never had any problems with it I generally pull three measurements for consistency on anything I measure when it comes to loading.
I want to take the time to thank everyone for spending the time helping me figure this out.
