Real world Airgun Velocity Database

[Colt25]

This topic is to post your real world chrony tests with different airguns. Rifle, or pistol.
Please include Average velocity, as well as Hi and Low velocity, the gun, the pellets, and the temp where you shot.

Are you looking for velocities of guns in stock configuration?

With all the possible combinations of custom modifications, accessories and pellet varieties, I would think this thread could get unwieldy very quickly.
