Penn Bullets New Coated Bullets ..... " These bullets feature our new polymer coating that was developed for military ammunition " ... This was the first sentence in his enclosed note about bullets that I received from him . They have no wax in the grooves ,just this purple coating that apparently is a 4 step process . Its first cast,coated,baked and then sized . Says this is a one coat application process unlike the "Hy-Tek" product that requires 2-3 coats . Bullets are for my .480 Ruger SRH and measure .476. They weigh 342 grs and plan to load them with 235grs of H110 . What say yee cast bullet shooters ?
