Gentlemen,

thank you for your information on this topic, here a quick review from the first visit to a 100m range:

Ammunition:
Sierra 55grs SPBT Gameking
Kemira N140
CCI SR
PMC case
OAL: 62,4mm

Rifle:
Sauer 80, special barrel in match contour 72cm long / 28" (!)
Leupold fixed 16power scope with a very fine crosshair

conditions: +5° Celsius, rain and strong wind

1st group starting load / 1st shot : bullseye !
4 shots within 27mm

second group ( +1 grs more):
4 shots in 12,9mm

third group ( +2 grs more):
3 shots in 13 mm, plus one flyer opening to 45mm

fourth group ( +3 grs more):
4 shots in 30 mm / primers getting flat
=> test stopped

Now I will retest the loads with +1 and +2 grs and in between, try other seating depths, selected/weighed cases and of course, benchrest primers.

As Ripp stated before, this might be a cartridge for even larger game than foxes, e.g. roe deer on grass plains at longer ranges :-)

@ Nitrox: prefered roe deer cartridge (highly biased)
I had very good results with :
- 7x57 with a 140grs Ballistic Tip at 780 m/s
- 9x57 with a 250grs SP at 640 m/s
- 9,3x57 with a 225grs RWS Doppelkern at 700 m/s

The standard 308 Win is too much / too damaging with the 150grs bullets, but loaded down to ca. 710 m/s a very fine and recoil-friendly cartridge for this small game
And: 9,3x64 with a 250grs Accubond at 800 m/s gives results, but might be on the overkill side...

best regards
Rolf
