One also needs to understand that statistically he must shoot a substantial number of groups at the differing ranges to accurately know what the rifle is actually doing.
I truly believe my statement that far more 1/2" groups are fired on the internet than ever fired on the practice range
It's been a long time since I've taken classes on statistics but can assure you that to say "my rifle shoots 1/2 MOA" requires a lot of shooting to support that statement....to say that it shoots different than 1/2 MOA at greater distances requires a lot more shooting.
Can you do this?.....place two targets at 100 and 200 yards distance and one precisely behind the other such that one only has to shoot through paper at 100 yards and therefore can measure the very same (10-shot) group at both ranges.....
This should prove the theory that the MOA is different at different ranges....or possibly disprove it.....I won't speculate!
