Hey guys, I am a newbie here but thought I would share what kind of performance I am getting with my 28. I played very little with loads and the 160 AB shot pretty good with 91gr of RL33 , fed215 . 3300 fps 1.0" groups at 100yards off the hood of the truck. So I tried 550yard off the hood and shot this 3.9" group . It was about a 50 kmh windy that day also. My gun has a 4-14 nightforce SHV scope . Seems like a great gun so far.
