Abstract: A firearm cartridge with a bullet including a body and a nose element. The body has a forward end, and an opposed rear end, with an intermediate cylindrical portion between the ends. The front end of the body defines a cavity that may have a cylindrical shape. The nose element is formed of a resilient material such as an elastomer, and has a first portion received in the cavity, and a pointed second portion extending from the forward end of the body. The bullet may be received in a centerfire rifle casing, for safe use in a tubular magazine rifle, so that the resilient tip protects against discharge of an adjacent cartridge primer by absorbing energy of recoil or other impulse. The second portion of the tip has a small meplat, and is smoothly contoured with the exterior surface of the front of the bullet, to provide an increased ballistic coefficient.

Abstract: A system and method for generating a controlled motion path with a machine-tool system having a controller operating in a servo rate. The method includes a first interpolation step, in which a path segment corresponding to a number of servo update periods is calculated. After the first interpolation step, a speed override factor is established. After establishing the speed override factor a second interpolation step occurs, which includes calculating a number of path setpoints for each path segment. The number of servo update periods per path segment may vary over the path.
