Oh Lordy, that is a vast understatement!
Was up in Big Timber at C. Sharps. There's a powerline outside with those blue glass insulators and one was about 300, maybe 400 yards distant. It was spooky how well it held the post just under the blue...........then my arms started giving out........
Quigley would have already fired but....
And by the way, a 42" barrel (not swamped) can balance pretty well, all things considered:
I'm not sure it will show on the image but it balances under the rear sight. The gun is 7.3# and the small bit of weight forward lets me do this at 50 yards and I'm a rookie with flinters.
