Model to real proportion of a 5.56x45 NATO cartridge in both loaded and fired (shell and poked primer).
The model is provided with textures already applied for the .blend file, otherwise as a model (.obj, .fbx or .stl) and PBR textures for it.
The base model (available in the .blend file) is 8 sided with 2 layers of subdivision (hence the pre exported models for the other formats are 24 sided).
