As I recall it was originally 4350. That was when DeMille and Hornady was developing. The "flavor of the month" says Winchester StaBal is the one.Can someone tell me what powder is being used in the Hornady 140 and 147ELD-M precision cartridges?
At one time Sierra manual development said N-150 for the 120gr & 142gr match kings. HTH
