PC: 20mmL113 should have rage of 2

[Mike Abberton]

To think a weapon such as the 20mm which has a muzzel veloctiy of 900 m/s and greater mass would have a noticably shorter range than an 8mm which had a muzzel velocity of only 755 m/s defies logic.

Muzzle velocity will typically increase maximum range, but increased mass often (but not always) actually decreases range. Heavier rounds are usually larger in cross-section, which increases their air resistance and slows the round quicker than a small round.
