What is the best way to make a blockable projectile?

Hello, I want to know what the best way to make a blockable projectile is. I have tried using touch but it isn't always the most reliable. I have tried using CFraming and Tweening but those don't work well with collision detection. I would like to what the best way is of going about making a projectile that can detect things that it touches. Also I would like to eventually make the projectile moved in cool ways (like curves and stuff). I know this will probably involve a bit of math but I'm not scared of it at all. Any resource that I could use to learn would be really great, or anything that points me in the right direction I would really really appreciate. Thank you for your time!
