How do you measure how well your rifle shoots?
average of all 5 shot groups @ 200 yds?
average of best 5 shot groups @ 100 yds?
average of favorite ammo with 3 shot groups @ 100 yds?
best lucky 3 shot group at local trash pit?
I personally try to use the average of my best 5, 5 shot groups shot off a bench with sandbags @ 200 yds(precision), AND all groups must stay in the same place with same ammo(preferably POA=POI @ 200 yds) from one shooting session to another(accuracy).
I just wonder sometimes when somebody claims "MOA" accuracy with their mass production rifle with commerical ammo, or surplus rifle. If I can get 1.5 MOA groups with a scoped rifle and hand tailored reloads, or 3-4 MOA with a surplus rifle and surplus ammo (using my method of calculating), I am very-very happy.
And just to be really anal while talking about "MOA" and angular measurments, should we be using the angle the group subtends ((radius/radian) X (180/pi)), (not a linear measurment) OR 2 X (arctan of (1/2 the group size/distance))(a linear measurment).
