As we know, two different things. Curious as to how folks assess accuracy. Measure POI from POA?
Moa as displayed on your target is neither a radius or a diameter, it is a straight line , center to center of the bullet holes. At 100yds this distance is just fraction over 1".That's how I do it. And in that respect, MOA is a radius, not a diameter.
I measure it as described by group size, measured center of hole to center of hole, at whatever yardage, usually 100 for easy math. Thus I say, “My Remington 760 is a one inch rifle, believe it or not.”Curious as to how folks assess accuracy. Measure POI from POA?
Thats the way I see it.It appears that there are different interpretations of accuracy and precision and what impacts them. Some think PRECISION ( group size ) is inherent in the equipment while ACCURACY ( POI in relation to POA ) is primarily shooter dependent. Some appear to believe that it`s just the opposite. That`s confusing to a neophyte rifle shooter such as yours truly. Real life example. Say I shoot 30 rounds from my .223 Savage 110. I measure the POI for each in relation to POA. Say The average of those measurements was .7". For practical purposes, is it accurate to say that that is sub-MOA accuracy?

The repetitive group to POA is the realistic measure of you, the gun, and the ammo.
To take it a step further, at least from a hunting standpoint, PBR/BSZ, for most people, is probably a better way to look at things too.

One thing for sure..100 yards damn sure isn't far enough to determine accuracy or precision.
We are looking at this different ways. Youre calling it the size of the group itself, Im calling it the size of the group in relation to the POA.You can look at it any way you want, but either MOA or inches, its about the diameter of the of the circle described by the shots, not the radius.
