I have been using
www.mastercast.net for my bulk lead bullet needs for about a year now, and just received my latest order - 5k of .45 185 gr swc, and 5k of .358 125 gr TCFP bullets. I have tried several other of the major players in the cast bullet market and have nothing but good things to say about Mike and Kate at Mastercast - their products are accurate, well made, and well priced. Shipping is fast and afforable too! They are every bit as good as higher priced bullets and much better than other economy bulk bullets.
