Sometimes we know too much:

My brother who knows NOTHING about firearms or air guns had a couple of rabbits eating his flowers. He goes to Academy Sports. Buys a cheap Gamo springer/scope combo based on fastest fps listed on the box. Buys whatever pellets were close by.

Sights it in at 15 yards with about 6 shots. Next day kills two rabbits. One at 25 yds and the other at 50 yards. My brother thinks I'm an idiot for spending 5X the money on my Weihrauch setup. Of course, I shoot 250-500 pellets a week and he hasn't shot his since killing the rabbits. Go figure.
