I found some SW Match Rifle to try in my quest to find a replacement to IMR 4064. Burn rate appears similar, based on SW burn chart. However, data is somewhat rare. Does anyone use this powder in 308 with a Hornady 168 grain Amax, 178 grain ELD, or a Speer 168 grain HPBT Match? The primary data from Shooters World is for the Sierra 168 grain Match King. While they're all similar, I'm not really willing to just substitute bullets, particularly with Hornady bullets. I'd probably try it with the Speer, but only if I can't find data by the end of the weekend.
