What is a more accurate way of detecting projectile collisions?

I am in the process of creating magic attacks and I have stumbled into a predicament. I have created a projectile launcher to simulate the effect of another player launching a magic attack.

This is the effect I want for all speeds for any projectile:

But this is what ends up happening if there is a high speed:

I am currently using .Touched, but I would really like a more reliable way. I have done some research and it looks like raycasting is a good away to go about this but a lot of the resources I have looked at are for bullet collisions. I want accurate collisions for parts of a reasonable size that will keep the same visual effects. Thank you for reading.
