The 308 will easily run 2800 to 2900 with a 155 Scenar. I was loading 48.5 gr’s Varget. I have since moved to 43.5 gr’s TAC for 2820 fps average. This is the exact same speed I harvested 50+ Axis & smaller animals with my 280 Remington running commercial loaded Remington 150 gr CoreLokt’s. 150 gr bullets at 2800+ is a terminal combination.
