I don't particularly have an issue with a true 2moa rifle for big game out to 500 or even pushing 600 yards. But My version of sub MOA, must be vastly different than most. I have used and seen quite a few really shot and have not seen a true sub MOA factory Montana bigger than 6mm. Even guys who swore that theirs was, right up until it came tme to shoot. Then there is all manner of excuses as to why it's not.

Have seen some that were 1-1.5 MOA and a bunch that were 1.5-2moa which is fine.
