The other f-class rifle in 6BRX (same reamer) has been giving me chrono readings near 3000fps with the 105 hybrids. The thing that I am more impressed with is the extreme spread of 5 fps on a 10 shot group with 33 grains of Varget and CCI 450 primers. My 6 BR using 30.4 grains of Varget is shooting around 2850, just to show you the difference in velocity by blowing the shoulder out. That difference at 600 yards will help hold a bullet in the 10 ring instead of being out in the 9 if you are a little off on your wind call.
