Accuracy: does the ammunition reliably shoot .5moa or better. If so, check-off part one as 'good.' .5moa is the level of accuracy I want from my longrange rig. .5moa is about 5" at 1k yards. If I can do my part in doping the wind and get a good trigger pull, .5moa = dead deer.
Consistency: make sure you shoot the ammo over a chronograph. You are looking for an extreme-spread (ES) of 15fps or less. If your ES is larger than 15fps, you will discover your groups will string vertically at 1k.
If you can achieve the accuracy and the ES, you are good to go.
