257 Firecat is a cartridge I developed for the AR-15. It has been tested and works fine in an AR but Hornady is so far behind on our custom dies that I put the 257 Firecat and the 366 Firecat on hold for right now. The 366 Firecat is based on the 308 case and works fine in the AR-10. On both we have to build the barrels from scratch which means it is a lengthy process and again we are so far behind I can't spare the time to build them. Hopefully soon.
