I almost bought a Crosman Nitro piston last week. It was rated at 1400 fps with magic pellets. With normal .177 I think I read where some guy chronoed it at just under 1000 fps.
That is still a lot of power.
Does anyone remember an episode of “The Rockford Files”, where Rockford has to hold off some gad guys with a pellet gun?
One of the reasons the single pump air rifles like the Nitro Piston are popular is that they do not lose a lot of energy from the heat of compression.
The Pre-Charged Pnenmatics are not as efficient because they lose the heat. If you are not doing the pumping, it does not matter much.
Don’t remember that one, but there’s this from Lock Stock an Two Smoking Barrels...
