The easiest fix for the Battlerifle is to swap the slug from the Shotgun muzzle velocity and, trajectory with the Battlerfiles base muzzle velocity and round drop. Go test it out in VR, take a base Battlerifle, shoot the static target on the wall. You can shoot it from the 10m range, then run back to 100m, and 200m, you will see with a scope that the round drops almost a full person at 200m. Repeat the test with the Slug shotgun, and it will not drop NEAR as much. I dont know if the SOE developers for PS2 have ever fired a solid 1once slug from a shotgun. But last time I fired my Remington 870 with a slug, it has better range than 00 buck but it still isnt a FN-FAL or a H&K G3.
