Home Forums Hunting & Shooting Ask The Gunwriters Fresh Evaluation of the "Copper Bullets"...

I couldn't leave it alone. For an initial velocity of 3,000 FPS and a 1:8 twist, you get 270,000 RPM. The centrifugal force on a .338 cal. bullet would be 349,933 Gs and for a .243 Cal. bullet 250,544 Gs. Don't know if that's meaningful to a copper bullet.
