As I sit here going whooophineewhoopeewhoop - across my lips - I got to wonder who taught you people how to measure and machine.
The hole in the primer pocket would be checked with a go / no go plug gauge.
You cannot measure the diameter of a bore with the straight edge jaws of a caliper.

My guess is that the factory uses a slight crimp when they manufacture their factor loads and that they do not put a slight crimp in the primer pocket in the brass that they manufacture for export.
We have had a lot of problems with the Remington crap lately - and buying a bag of new brass with issues does not surprise me.
I myself - I'm not a fan of turret presses and the turret press leaves a lot to be desired when it comes to accuracy. I came from the old school - where you do it once, do it right and move on.
There is no way for sure for this person to know how the primer felt as it was being pressed into the pocket - because it probably doesn't take 5 lbs of pressure to press the primer in the pocket. Personally - I wouldn't give a nickle for a turret press - but that is just my opinion.
I would say for you to take a couple of those rounds and put them in a single stage press and try them again with a new primer. Then if the primer falls out - measure the diameter of the primer.
Then again - if you do not have a micrometer that goes to the .00001 and if you do not know how to use a micrometer that goes to the .00001 it isn't going to do you any good anyways.
Probably your best bet is to pull all the bullets, dump all the powder, take the empties back to where you bought them and ask for a refund.
As I sit here , all crippled up from cleaning brass for the past several days.
I can't help but wonder what were the people in Eau Clare Wis, Twin Cities - Minneapolis Minn, Philadelphia PA, Salt Lake City - Utah, Lake City Mo doing in 1943 - 57 when they were making this brass for the military. And - would they have a job if they made the junk that the ammo manufacturers makes today.
