Excuse my naivette, but is there a source of Grendel brass from other cartridges. I just started reloading, and you gentlemen turned me on to using 308 for 260 brass; so I was hoping that there was a similar possibility for the rare/expensive Grendel case. The ammunition will be used for a 20" AR for target shooting. Thanks in advance for any suggestions. By the way, a buddy of mine already tried 220Russian and PPC to no avail.
