So everyone has been indoctrinated into the idea you need a level to succeed. Especially when shooting inside a 1000 yards on relatively flat surfaces, especially resting the rifle on a sand bag where gravity actually gives you a hand.
So we were playing around at the range yesterday, we were...
Specifically the AR-15 in the sitting position for HP Service Rifle NM competitions. i.e. shooting in the sitting position at 200 and 300 yds.
In order to get a muscularly-relaxed position in sitting, that damned AR-15 is canted like hell....maybe 10-20 degrees, I'd guess. I can straighten it...
