I would be interested in the damage values in the configs for the different types of .303 in the game. Does anybody know whether someone extracted that information from the game files.
I now dumbed the Incendiary/Tracer (White) rounds in the two outer guns and substituted them with Red Tracer 800yds ball ammo, since I saw little to no effect of the usage of the Incendiary Tracer rounds. The universal ball rounds seemed to have more punch in enemy planes as I tried it today on the Repka Steppe server from my point of view.
I now fly around with:
1.)Tracer (Red ball)
2.) Ball
3.) Armor piercing
4.) Incendiary/DeWilde HE
5.) Armor piercing
6.) Ball/ DeWilde HE/Ball
7.) Ball
8.) Tracer (Red Ball)
I nthe future I try to investigate the ammo effects with more objective measures like recorded tracks

. I hope they are working now.
