Converted my .25 Walther Falcon Hunter to Nitro Piston

[AirHunter4Ever]

Using the same pellets after the conversion, the fpe jumped to 33! It also shoots much quieter with a softer hold now.

That is what I was referring to as being a loss of power from 33 fpe to 25-26 fpe, which I don't consider to be a slight drop.
