A modified projectile for the .308 cut away model by Johnny No. 5 (https://makerworld.com/en/models/187510#profileId-300020).
I wanted a hollow point boat tail variant of the projectile, so I modified the full metal jacket one that came with the original model. The top of the projectile isn't cut 100% flat (I think because the jacket isn't completely square to the build plate), but it's close enough for my liking.
