PTI Machine specializes in manufacturing some of the highest quality ballistics testing supplies available on the market.  We stock a full line of fragment simulating projectiles (FSP's) and right circular cylinders (RCC's).  Standard FSP sizes include 22 caliber (17 grain), 30 caliber (44 grain), 50 caliber (207 grain), and 20mm (830 grain).  Our standard fragment simulators are made to the latest edition of MIL-DTL-46593B (Amendment 1 August 11, 2008).  Other common FSP standards used include STANAG 2920.  Standard RCC sizes are 2 grain, 4 grain, 16 grain, and 64 grain.  Drawings and specifications are available upon request.  We strive to hold the tightest tolerances possible on all dimensions, mass, hardness and finishes.
