I have not seen this on the USA steel cased 90mm before, am I right in assuming that the plug at the side of the primer is for "high pressure test" ! any information will be appreciated

The plug is for loading powder from the case head. The projectile was a Fin-Stabilized HEAT round with a long boom. It was the only way to load powder around the tail. The 105 Recoilless Heat was loaded in the same way.

thanks for that HAZORD, it does make sense
