Sorry it took so long, I had to leave town on business. My load for the 68 gr Hornady is 25.5 gr Varget, CCI BR-4 primer, Winchester new unfired cases, the velocity is 3,025 fps average. SD is 14 fps. I shoot at 4,800 feet elevation, and this is a winter load for me. I load them to the maximum length that the AR-15 mags allow. The 69 Gr Sierra will out shoot these by about .2" at 100 meters.The firearm is an custom AR-15 with a Lilja 25" 3 groove 1-8" twist barrel.
