I was doing lawn work this AM when a horse fly began harassing me. I retrieved my Crossman 397 from the patio and locked and loaded (two pumps/Crossman Premier .177 pointed pellet). Stalking back to my push mower, I spotted him/her taking a break on the grass catcher bag, presenting only a side profile target. From five feet I squeezed off a shot, neatly clipping it. I finalized the occasion with a butt stroke.
I'm so proud of myself that I have to share the experience with y'all.
