Intro This is a to 1:1 scale .50 BMG cartridge, which many firearms are chambered in, most notably, the M2 Browning and Barrett M82. Use Use only for discussion piece. I am not responsible for use as a weapon or any other malicious action. Design I changed the rim slighly to make it easier to print. This change should prevent it from being able to be chambered in an actual rifle chambered in .50 BMG. There is a small cut out in the bullet, where you can run a wire to hang on the tree! If requested, I'll also give the option to hang it from the casing. Perhaps from the primer pocket? Printing 10% infil is fine, with 1 shell. I recommend you swap filaments when the bullet begins to print. Make sure the orientation of the print is the nose facing up!
