I have a FWB 124 that is great with no wind, like in a barn shooting pigeons and starlings but get it outside and the wind controls those pellets.
I have a .25 caliber pcp that will put 5, 10, 20 pellets in the same hole, not cutting the hole, the same hole, at 25 yards. Wind is always a factor with pellets but on a calm day, it’ll shoot 1/2” at 85 yards. (Length of my backyard range). 25gr pellet moving about 850fps and I get 140 like that with one fill. It’s rough, really rough on pigeons!

My favorite rifle!
I just don’t see the value/need for the 21 sharp and I don’t think it will be around very long.
