125 mm smoothbore ammunition

The following is a list of ammunition fired by the 125 mm smoothbore gun series used in the T-64, T-72, T-80, M-84, T-90, PT-91, T-14 Armata, and other tanks derived from those designs, as well as the 2A45 Sprut anti-tank gun.

APFSDS-T

Armour-piercing fin-stabilized discarding sabot tracer or APFSDS-T rounds. Typically used against other modern tanks.

There are different ways to measure penetration value. NATO uses the 50% (This means that 50% of the shell had to go through the plate), while the Soviet/Russian standard is higher (80% had to go through). According to authorities like Paul Lakowski, the difference in performance can reach as much as 8%[1]
