You remember how we were taught that in the offhand position you draw a figure "8" and squeeze the trigger at the crossing point of the "8"?
You don't have to draw a figure "8" with this weapon!
As heavy as it is, you can hold it on the target in the offhand position. The balance is perfect!
I have never seen any weapon as well balanced as this rifle!
I have no doubt that Quigley could have shot that bucket at five hundred yards over and over in the offhand position.
