Yes, I’m adding drag to the later update, which will also make a difference too 
However, the current projectiles in 1.0 already include bullet drop as an inherent property of the original projectile class. It may be hard to notice in the small confines of the test level but gravity does pull the bullet downwards. There is a float in the projectile blueprints if you open them and click on the ‘projectile’ component called “gravity scale”, you could multiply the gravity scale to add even more aggressive bullet drop if needed.
