I am in the process of buying a 16.5'' Alexander Arms upper. I'm also in the process of acquiring stuff to cast bullets and want to cast for the Beowulf. Now I seem to be having a hard time tracking down a good mold for it. Does anyone have experience with this cartridge or reloading lead for a rifle cartridge of this size. I have around 300lbs of lino type lead. Will this mold work for a Beowulf: http://www.midwayusa.com/viewproduct/?productnumber=266944 It states it's for a .500 S&W.
