What does .177 caliber do best?

.177 is the most popular caliber worldwide, the only caliber accepted in international 10-meter Olympic competition, and the cheapest to feed.

Pellets are light and fast, giving the flattest trajectory of any common airgun caliber, which is why target shooters prefer it. It is a fine pest and small-game caliber inside about 25 yards when you have at least 12 FPE and place shots well. The drawback is less knockdown energy than larger calibers at distance.
