US12339106 - Fiber reinforced bullet and method of manufacture

Bullet constructed from FRP, preferably basalt. The method includes the step of forming pultruded basalt strands positioned co-axially before milling to form a conventional bullet shape. The process uses a 10 mm FRP rod held by a revolving collet that is interfaced with an upper diamond OD grinder and a lower diamond profile wheel. Gravity allows the rod to rest on a Teflon coated cut off wheel. The upper grinder draws the rod to an exact outer dimension and the lower grinder cuts the bullet to a perfect dimension. Linear slides move the cut off wheel and grinders in for the cutting process and out to allow the finished bullet to pass.
