Shatter gap - When lower velocity is better | Armor Penetration Simulation
The shatter gap is the range of velocity over which the projectile cannot withstand the stresses on impact and is shattered. Therefore, the energy of the projectile is dissipated and the penetration values do not increase proportionally to the speed. In addition, projectile with explosive charge loses its ability to explode due to damage to the chamber.
76mm M62 (7 kg APCBC* projectile) at 720 m/s & 783m/s

*without ballistic cap to shorten the calculations
Sherman 76mm M1 gun muzzle velocity - 792m/s
720 m/s refers to a distance of approximately 700 m,
783 m/s refers to a distance of approximately 100 m.
