An interesting post from a new (to me) blog I am following. Vuurowapen Blog.
Accuracy can be subjective.
For example, if I said that I had a pretty accurate rifle, but did not clarify that statement, one listener might think that I had a rifle that could shoot .5 MOA (1 MOA = 1.047″ at 100 yards), while another might think that I had a rifle that could shoot 2 MOA. The first guy might think that I based my statement on a single three shot group. The second might think that I fired ten shots.
