Grackles the finest airgun target God ever invented. BTW, when are they NOT a nuisance bird? Which brings us to
the greatest airgun story you'll ever read if you have a sense of humor.
I was managing a bicycle store in the Dallas area in the 1980s surrounded by trees that were apparently fantastic for grackle roosting, loitering and partying. Suffice to say the shop sidewalks were their toilets. I decided to do something about it.
At the time, I had a fantastic Japanese-made Sharp U-FP .177 Co2 pistol with a simple (detachable) shoulder-stock. It shot medium weight pellets 550 FPS with match-grade accuracy.
I also had a very "unique" employee named Paul that was a fantastic salesman, and considered himself a Buddhist. Yet he (eventually) got into fist-fights with customers on two different occasions.

Reminder-
1980s,
DALLAS! I showed up to work about a half-hour early one day to put a dent in the grackle population with the fantastic little Sharp rig. I'd dropped about three grackles from the driver's window of my truck when I see Paul stand up from where dead grackles had been raining down.
Paul walked over and said, "
What the hell are you shooting?" I'd dropped those grackles almost on Paul's head while he was sitting cross-legged outside the back door of the shop doing his morning Buddhist chanting!
Of course he and I became fast friends.
