Understanding the Stats

---

Hit	TypicalSpeed	AirFriction	Caliber
Hit is the potential damage capability of the round. The higher the number the better, however if it has a low typicalspeed, high airfriction or a low caliber the damage will drop off massively from its Hit stat.	Typical speed is the typical speed that the ammunition will travel at. It is measured in meters per second. Ammunition below 350 m/s is subsonic.	This represents how much the air affects the round. The heavier the round the more friction it will encounter. Numbers further from the 0 such as 0.0004 is less friction, close is more friction 0.04.	Caliber is the raw armour penetration capability of the round. The higher the better.
