Using FastCast as HitScan?

I’m making a gun system, and i’m going to be creating a fake bullet on the client for cosmetics, and a real invisible bullet on the server for damage. I was wondering if there was a way to make the bullet travel instantly to help with latency, I tried increasing the speed of the projectile but it also changes the path.

( The reason i’m not using hitscan entirely is because I still want the benefits such as bullet drop and the cosmetic travel time, without the downsides of latency and hit detection. )

The bullet will hit instantly and still have bullet drop, but on the client it will just appear to have travel time.
