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 performance is very confusing:

Edit: Ignore the Cv 90
