currently the trajectory is minimal depending on caliber, largely depending on typical speed/ initspeed relation.
To find the correct ordinate for cartridge/weapon configuration i need a certain relation between typicalspeed/initspeed, which also sets a certain hit value and penetration at a certain distance.
In real life a higher kinetic energy/velocity does not equal a higher wound effect.
It would suffice if there was only ball ammunition or only armor-piercing projectiles,
but across ammunition types/shapes, you cannot make differences clear between ball, hollow-point, steel penetrator, armor-piercing or open tip match projectiles.
e.g. an M885 steel penetrator cartridge has the highest penetration roughly the closer one is to the muzzle. The terminal ballistics in soft tissue show, that with the higher the velocity is , the smaller the destroyed area becomes, because the projectile does not tumble at impact.
This way the most destructive velocity only commences much later ( havent calculated it yet ), maybe at 150 meters, and beyond that it becomes less effective.
Also the highest penetration for a similar projectile, but purely lead is the M193, which is softer and less resistance to soft issue, will have the maximum wound effect ( almost same amount though ) at roughly 25 meters.
Without this effect the injured person can still remain partly combat effective and even survive its wounds.
Therefore another variable to set the kinetic energy/projectile resistance combination is necessary to set the highest value at that velocity for penetration.
