Hello all -

I'm not the best shooter in the world. I was able to shoot an 2 MOA group with IMI Razor Core 77gr. There were definitely some user-induced fliers. The mean radius of the group, however, was .66". My question about mean radius is as follows: if I'm trying to determine the accuracy of a round, Say the IMI razor core, is it better to use the actual MOA size of the group, or multiply the mean radius by 2? Theoretically, that would give you the diameter of a group you could expect.

Any input on this guys?
Thanks
