Need Help, tune mv or bc

Broke down and ordered my self a lab radar to verify the mv provided to me by my gunsmith. So I went out this morning and here are the results.
This is hornady 140 eld-m in a 20" proof 6.5 creed. Radar gave me a average of 2638. But to match my drops. I am having to program my br2 and the StrelokPro app to 2550 FPS. After the pic. I Shoot 20 round and I am far from impressed with this factory ammo. High was 2667 low was 2607. Time to start reloading I guess. Gun shoots great, that group was at 300 yards. But it opens up with longer range. I am assuming because of the spread in MV with this ammo.
