The Trophy is made in .25.
I have held but not shot a Harper Wolf in .25.
My Wolf is .22 and with a light .25 pellet I don't see why the bigger calibre would not be fun.
Wish I had bought the .25 Wolf when I had the chance.

After a stressful week I require air pistols that blow holes in baked bean cans and/or send them flying.
Not shoot little holes in target cards.
Although I do have that type as well.
Way back when I fired a Harper converted Saxby-Palmer Orion Six TAC revolver. I got all six pellets into a 1/2" circle two-handed at 10m. It was totally cool, it even recoilled a little like a rimfire loaded with .22 Short.
The velocity seemed fine, when I asked the owner there was some evasion but finally I got the impression that it was fine because it was putting out 9 fpe!
The Umarex S&W 586/686 revolvers are capable of .25 calibre conversions. It requires some drilling of both the breech and the mags as well as a custom threaded barrel but it is doable.
