Answers.Text: Ah, it seems I have misunderstood the question and thought you were requesting help with a magazine that stores the cartridges in a spiral, as in a Calico Liberty. But thanks to your edit it is now clearer what you had in mind.

Comments.Text: I mean why not reverse engineer the same solution visible on the photo and in the video? As far as I see it is just a simple arrangement of common beams to form appropriately angled slopes. Take a few more screenshots where the video shows the assembly from slightly different angles and with a bit of trial-and-error you should have the exact copy soon.

  (Asked by: username_0 on 2024-08-04)
  
  I need help designing a Lego magazine for my Lego p90 gun project. If you don’t know, a p90 magazine twists the bullet's orientation in a spiral. I need a way to make that in Lego pieces. Is there any way to make this? I was going for a mechanism like [Snyzer Tech’s P90](https://www.youtube.com/watch?v=fg7US4gASFA):

  If I were to start this project, I'd consider using the [spiral staircase pieces](https://www.bricklink.com/v2/catalog/catalogitem.page?P=40243&name=Stairs%20Spiral%20Step&category=%5BStairs%5D#T=C) to build a curved staircase and see if it can work sufficiently with the rest of the mechanisms and scales.
