Web2 aug. 2010 · A bullet spins because the gun barrel is designed to put spin on it. It has spiral grooves that dig into the surface of the bullet (lead or copper usually) and cause the bullet to rotate as it goes down the barrel. A rotating bullet is more stable than a non-rotating one because it has angular momentum. Web27 jan. 2024 · Assuming the same MV of 3000 FPS, the bullet makes 12/8 or 1.5 revolutions for each 12″ or one foot it travels in the bore. Accordingly, the RPM is 3000 x (12/8) x 60, or 270,000 RPM. Calculating the RPM based on twist rate and MV gives us some very important information.
