All medium calibre
Forty-six line items carry a high-explosive nature. The designation families run 20 mm x 102, 20 mm x 110, 20 mm x 110RB, 23 mm x 115, 23 mm x 152B, 30 mm x 165, 30 mm x 173, 30 mm x 210B, 30 mm x 220, 37 mm x 252, 40 mm x 311, 40 mm x 365, 57 mm x 348 and 57 mm x 438, in plain HE, tracer HE-T, incendiary HEI, HEI-T and pre-fragmented PFHE suffixes. Every record states a projectile mass, a muzzle velocity and an operating temperature band; explosive mass and fuze figures appear where the source records them.

Tender schedules name this nature by cartridge designation and suffix rather than by projectile alone, so a line reads 30 mm x 165, HEI-T before any figure follows. Buyers then match round mass, projectile mass, explosive mass and the muzzle velocity band against the gun already on strength. Mean maximum gas pressure and the operating temperature range complete the acceptance envelope quoted in most entries here.
Suffixes separate the models. HE states explosive mass alone, HE-T adds a tracer element, HEI and HEI-T record an explosive incendiary filling, and PFHE marks the pre-fragmented projectile lined with tungsten balls in the 40 mm x 365 and 57 mm x 438 entries. The 30 mm x 165 family is split further into aircraft, autocannon and naval loadings that differ in muzzle velocity and round length, with a self-destruct time recorded on the autocannon and naval loadings only.
The suffix records the documented filling. An HE record states an explosive mass on its own, while an HEI record states an explosive incendiary filling. Several families quote the same projectile mass for both, so the suffix and the filling line are the fields that distinguish them.
No. Self-destruct timing appears only where the source records it, for example 4.5 to 8 s on the 20 mm x 110 entries and 13 to 19 s on the 30 mm x 165 naval loading. Entries without that line, such as 57 mm x 438 HE, quote a fuze arming distance instead.
