Re: 7mm reload problems (ballistics)
One thing you could try is shooting/chrono some Federal premium in 160 gr Accubond. I got 2921 FPS, out of my 24" barrel, which seemed about right vs. the reported 2950 (26" barrel) with those rounds. If you can get around 2900+ FPS with those factory loads, then you should be able to work up to it with your components.
If you like your hunting rifle, you can keep your hunting rifle.
