Ive loaded 30.5 and 31.0 grains CFE223 powder and CCI 450 primers in both Lapua and Hornady cases with 120 grain Sierra Pro Hunters. Most of my Pro Hunters were factory seconds but still shot good for me out to 200-300 yards.
A Friend goes to Wy every year to hunt antelope and usually gets one every year. He has taken most antelope with the 120 grain Nosler Ballistic Tip and around 29.5 grains of Accurate 2520 in Hornady brass. When Accurate 2520 was unavailable for a few years he switched to 31.0 grains of CFE223. This friends first 6.5 Grendel is 24 inch AA which he used to take an antelope at 416 yards with 120 grain Nosler Ballistic Tip. He has used an 18 inch 6.5 Grendel the last few years with good results. My Friend usually verifies his zero upon arrival in Wy and usually hunts around 7200 feet ASL. Since he lives at much lower elevation in the midwest and the different temperature range verifying his zero has helped off set change in velocity with lower temperature.
