I finally had a Sunday off so I went down to Kurrimine Beach Rifle Range and got to do some work on the 7mm-08.

Basic stats:
Remington 700 Mountain SS New Model with Bell & Carlson Stock. 22" barrel.
Norma Brass
Federal 210 Primer
Hornady AMax 162gr
ADI Benchmark 8208 Powder. Recommended ADI 40.2gr & 2725fpm in a 24" test barrel.
Standard COL 2.80" / 71.12mm. I loaded mine to 71.14mm COL.

Sea Level, 27 deg C

The rifle is brand new, no bedding yet and an old style trigger fitted that has been gunsmithed to about 2lb pull. Scope used was a Nightforce 3.5-15x50.

All loads produced 1" to 1.5" 3 shot groups. More my lack of practice, but a good start.

3 metre velocities as follows:

38.2gr
1. 2645
2. 2637
3. 2637

38.7gr
1. 2678
2. 2641
3. 2666

39.2gr
1. 2686
2. 2684
3. 2658

39.7gr Most consistant, widest group 2"
1. 2695
2. 2698
3. 2686

40.2gr Max ADI load
1. 2715
2. 2725
3. 2728

40.7gr Group 1.25" second best group.
1. 2723
2. 2745
3. 2763

41.2gr Smallest group just under 1". Slight pressure signs around firing pin mark on primer. Still easy to extract.
1. 2774
2. 2793
3. 2781

I did not expect these velocities from a 22" barrel.
