Well Bob there is a 30 min window to edit posts. Oppps I reread your original post and have to repost to correct my errors.

Hi Andy, ... and thus proving that desperation is the father of invention. An idea after my own heart... superglue as a tool to increase pellet weight. You machinists can chuck that in your lathe and spin it Huh? he he he

Seriously, Bob I am impressed. I really appreciate you guys doing all the heavy lifting. Of course I have a question for you Bob.... So if we look at velocity at impact...?

Theoretically the Youtube "dealer" advice that you cannot take any type of small game with .177 or with CO2 would be a marketing driven conclusion.????

From your charts I might assume that maybe even a detuned CO2 target pistol in .177 could possibly be adequate for small pest extermination... based on muzzle velocity, close range, and mathematical constructs; assuming average muzzle velolcity and then crunching the drag numbers to get fps at distance of the intended impact.

Thanks guys,
