I target practice all the time & squirrel hunt to get the lead down pat before deer season. Because I deer hunt with a .300 blackout 8.5" barreled AR pistol. I can hold a hardball sized group at 100yds & hit deer in a full run like I did this one a few weeks ago.
It was opening morning I saw this one running through the woods, I gave it a bleat to get it to stop but it dropped it's head & ran faster. I pulled up the gun took quick aim & squeezed the trigger. The doe jumped, gave a kick & piled up after about 20 yds, she was about 50 yds away when I pulled the trigger. It was a good double lung shot.
