I went out and tested the 85 gr load this morning. 3 shots measured .269" CTC. The sun was just coming up so the chrono didn't read too well. We didn't have enough time to set up the infrared system but I know it will be right @ 2850 fps + or - 10 fps. This load is VERY accurate @ 100 yds. I'll test it out on a doe this weekend.
I have the same rig. Try 96.0 grains of RE25 behind a 180 Nosler Accubond, Fed. 215M primer. I think you will like it. 3350 fps. Very nice groups. Dead crow at 340 yards last week with this. Work up from below, watch pressure signs. Good luck.
