I made theimage bigger and brighter, and i can't see anything in the primer pocket that shouldn't be in there...
Over the years i've run onto cases where they just plain was hard to get primers into.. I think this is one of those cases...
I have used a neck chamfer to take the edge off of the primer pocket to help give the new primer a better start... Don't get carried away doing that though!

" I have to disagree, I have 1,000 pieces of PMC 223 rem brass I had saved after popping off the whole case in my mini-14, I figured one day Id reload it.
The day did come the first case I tried to resize caused the decapper pin to push up out of position on my die. thinking maybe the decapper pin was just loose I reset it and tightened it up and proceeded to decap and size another case it happened again. I now had two 223 rem case where the primer buldged out but did not leave the case it was also a pain in the rear to get these cases out of the shell holder. I brought these 2 cases and a hadful of a few others and showed them to a friend turned out these cases had a military style full circle crimp on the primer pocket. the headstamps are marked as 223 rem not 5.56 like military ammo. Id have to say it is very well possible that his cases might have a crimped primer pocket."

I stand corrected! That's what I get for not keeping up with what's happening in the .223 world!
It is certainly easy to tell if the primers are crimped in! as you say, it puts a strain on your decapping equipment. In addition, the pocket crimp ledge has to be removed in order to get the new primers in (usually). But this is also easy to do. If you have a lot of cases, it is worth getting one of those "primer-pocket crimp-removal swagers" like RCBS makes.....
