About the velocity of the VT shells of the Lvkv 90 40 C

Hello. I was comparing the bullet velocities of the Lvkv9040C and the M247 VT, and the Lvkv9040C’s bullet velocity was 1015 m/s, while the M247’s was 1100 m/s. Why is this? Both are equipped with a 40mm Bofors L/70 cannon. Is it because they use different ammunition? Can someone explain?

Both vehicle’s nations produced their own ammunition, so there’s small differences in specs.

To be frank L/70 rounds performance is very confusing:

Edit: Ignore the Cv 90 AP


To be fair, The Sgt York and the VEAK 40 are the closest comparable vehicles. And the performance difference is insane
