Gamo Paratrooper power output
Has anyone ever put their .177 Gamo over a chrono ? I was wondering what the normal power is. Had a very weak rifle which I just renovated. Decided to replace the leather seal with polyurethane but the limit still seems to be around 8.5 ft lb. Probably limited by the small swept volume of the chamber. Must admit I put a shorter spring in as I did not fancy trying to compress the 39 coil original one.
