I have a Cooper Pheonix 6.5-284 and I am shooting the 140 Berger VLD hunters. I am getting groups in the .17 range but that is at 2660-2670 fps. When i bump the load up to get 2850-2900 fps my groups jump to the .4-.5 ranges. I REALLY like the those little groups but it the FPS more important in the hunting world at distance than the group size. Hoping someone shooting the Bergers at distance has some input on this. I mainly hunt Whitetail, Antelope and Ground hogs. For bigger game I use my 300 RUM or hopefully my new 338 Lapua that I haven't starting shooting yet. With the 6.5-284 I would likely keep the shots under 1000 yards. Farther than that I would go with the bigger rifles.
