I am a Maya modeler, but the one way I would think of doing this (Take it you are doing the High poly of the magazine), is taking a helix or spiral spline and extruding along this spline and creating this geometry this way. Or you can use a flat geometric spiral of some sort to match this spiral, and extrude along that.
Like Kyle said, make sure this is floating geometry as you will want to keep the drums themselves as clean topology as possible for a High Poly. Just how I would do it right this moment. Havent made anything like this before, but seems to be the most effective way.
Very nice result, I am glad to see that you modeled it in.
Add3r: Floating geometry can be used to save time, but if you can model it in, then do it. You get incorrect shadows when you bake your AO if you used floating geo. I am not saying to never use it, but there is no case where you should "make sure this is floating geometry". Colditz did a great job of getting the details in seamlessly and this will give a better result in the end.

You can disable backface shadow casting to alleviate most of those problems (in xNormal, for instance).
Only small updates. Used for Patronentrommel 34 PT34 and Doppeltrommel 15 DT15.
DT15
The DT15 or "Doppeltrommel 15" is a 75 round magazine intended for use with the MG15. Except for some inside mechanicals, its almost optical identicial to the PT34 or Patronentrommel 34 used later for the MG34. Because of mechanical reasons, the DT15 will not fit on a MG34, but a PT34 can be used on the MG15.
PT34
The PT34 or "Patronentrommel 34" is a 75 round magazine intended for use with the MG34. Except for some inside mechanicals, its almost optical identicial to the DT15 or Doppeltrommel 34 used for the MG15. The PT34 will fit on a MG34 and the older MG15. When used for the MG34 it needs a special cover, the so called magazine holder or "Trommelhalter". It can't be used with the usual feed cover used for belts.

If you're doing a high poly, you could try floating the shape over the surface and bake it down.

Create a Helix Spline -> Splines -> Helix
Adjust the settings.
Thanks a lot.
