A little over two years ago I built a match rifle to shoot 7.5X55 GP11 (Swiss Gov't Ball) ammo exclusively. Here are a few pictures. The action is a blueprinted Remington 700 with a one-piece oversized bolt (.704") from Pacific Machine. The action is reamed to .705" so the fit is very close and precise. The rail is from Nightforce and the trigger is an X-treme Model 22. The stock is a McMillan Baker Special with three way adjustable butt and thumbwheel adjustable cheekrest. The barrel is a Brux with a standard Palma contour and is 28" overall. The bore is .298"/.306" with a 10.5" twist in Chrom Moly. The scope is a Weaver CT-10 with a 1MOA dot and fine cross hairs. A little coarse for real precision shooting but works very well at 600 yards and out in marginal light.
Got out to the range this weekend to give my Swiss rifle project a full workout. Shot it on Sat and Sun and went through about 40 rounds. Here are the last three groups. The two side by side are one lot with a scope adjustment to separate the groups. The second target is the final sight in. All shooting was 5 shot groups done at 200 yards from sandbags over the back of my truck.
Based on my experience with this cartridge, reloading it with 168/175 Sierra Match Kings will cut the group size in half.
