30×173mm (Bushmaster II) is described as:

30x173mk268apfsds-55mm/60/1000m

30x 173 Oricon FAPDS-3 1 mm/60/1000m, 25mm/60/2000m.

I can't prove the source, so let's take it as a reference.

Old 20×102mm ammunition;

Aircav.co (sorry) m/ cobra /ammo20.h (sorry) tml

M56 HEI: .25 inch (6.3 mm), RHA at 60 degrees, and dip angle at 22 1 m; 0.50 inch

(12.5 mm), RHA 0 degree, dip angle104m.

M53 API: .25 inches (6.3mm), RHA is 0 degrees, and the inclination angle is 1 1,000m.

M940 MPT-SD:0.25 inch (6.3mm), RHA of 60 degrees and inclination of 940m;

.50 inches (12.5mm), RHA is 0 degrees, and the inclination angle is 518m.

The PGU-28A/B currently used for tactical aircraft is unknown.

Among 20× 102mm, depleted uranium MK 149 is the most penetrating one. The latest MK244 seems to be stronger, but this one has not been found yet.

In addition, in the possible conflicts in the future, there will always be one side that uses less anti-tank ammunition and is usually the stronger side. The United States and Israel generally use less anti-tank ammunition than each other because their opponents have nothing to fight.
