without the fastcast?

What’s the problem with using FastCast? A tool is there to ease beginners and experienced developers.

I’ve tried using Heartbeat to update the CFrame but it makes the hit detection really unreliable.

According to the Roblox Documentations,

The Heartbeat event fires every frame, after the physics simulation has completed. The deltaTime argument indicates the time that has elapsed since the previous frame.

Here’s the order of the steps.

Your best bet is to use runService.PreRender or runService.RenderStepped in replacement of the Heartbeat.
