Winchester .308 Rifle Bullet

Winchester .308 Cartridge and Bullet This is a .308 rifle cartridge and bullet (and primer) made by Winchester. To create a "dummy round," you can print it using a dense setting. However, if you print the cartridge hollow, the bullet will not fit in the case because plastic shrinks and tolerances were designed for brass. When loading bullets, brass is widened then crimped - same goes for the primer. Print Settings Printer: M3D Rafts: No Supports: No Notes: For making a dummy round, use a solid fill and high resolution to achieve a smooth surface. Post-Printing Post Processing Required You will need to smooth out the part and check its tolerances. This design was created in AutoDesk 123D using data from Sierra Bullets Reloading Manual for the Winchester .308 Cartridge.
