Pic related is my original design. The teacher just told me that my design and mechanism is basic.

You know that cheating in education is cheating yourself, right? I would assume that the point of the project is to teach you how to translate vague ideas into buildable schematics and then get a practical understanding of building to those schematics. So get to it.

I'm a total gun novice but I can't see how the lever for the next shell is getting triggered to load in?

And your sketches aren't giving me a great insight into how you plan for the mechanism to function either.

I'll be honest, sometimes the simplest way is the best. My machine just drops the used one into its bucket thing, and I put a new one in the top. Gravity, man.

Do love that your teacher called it "basic" though.

Im on 2 percent so ill be afk for a while

A spring, which is overcome by the stronger spring driving the bolt.

So what are you looking for here, then? Some way to make a blowback-operated coffee machine? Protip: Given the lack of blowback from conventional coffee brewing, you'll need a different power source.

Correction, found the video that gif is from. Looks like a cam driven by the bolt spring, though that may be linked to the shell ejector spring, which cycles at the same time.
