Whats the best way to make gun system projectiles?

Title is basically it. I use fastcast but it seems outdated, last updated 2021 when i use it there are small frame drops, trying to get as little as possible

Have you tried using fastcast with partcache?

That did the trick for me.

Yes i did, however this is exploitable because it fires a remote to the client and the server shoots the bullet, i can do tool.activated on server but my gun is AUTOMATIC meaning i have to user userinputservice…
