The penny is for scale. 5 shots each of Aguila Colibri and CCI Quiet 22 solids (not the segmented bullet) at 27 feet from standing using a Winchester Model 47 with the issue open sights and with light on the target and behind the shooter. There is one pulled shot but the gun is backyard squirrel-head capable with either load.

I mostly shoot the Colibri and this has deposited some crud at the front of the chamber. It is highly advisable to clean the chamber before shooting ammo with a "regular" bullet in it. For those who might not know, the Colibri bullet looks more like an airgun pellet and it is commensurately short compared to the standard 40-grain RN of the Quiet22.
