[QUOTE="Warren Jensen, post: 21098, member: 21"] Blaine, Please explain your Mach 1 number. Remember, we are speaking of an environment of several hundred if not thousands of pounds per square inch and temperatures of greater than 1000 deg. F. The leading shockwave on a flatbase bullet, flying backwards at supersonic velocties would be way out in front of the bullet. As to whether to evaluate a rebated design on whether it is superior or not in venting or controlling gas flow in the first few inches after the bullet leaves the muzzle is fine. Remember, it is demonstrably not superior after you get 10" downrange. A rebated designed will increase drag, at supersonic and subsonic speeds, and will add instability at transonic velocities.
