I've found a crazy accurate load out of my .300 WSM Browning A-Bolt - it's routinely shooting under .5" at 100 yards using 67.0 grains of IMR 7828 and 180 grain Sierra Gamekings. I don't have a chronograph, and I'm getting differing FPS ratings between the Nosler and Sierra load manuals. Nosler shows roughly 2,900 FPS while Sierra shows 2,700 FPS...Thoughts on what this load might actually be running? Thanks in advance!
