Good shooting without a doubt BUT as those of us who use FAC air quite a bit know, once you push the range over 50 yards everything depends on the wind.. This is especially the case with the JSB 15.9 grain pellets which are nowhere near as stable in the wind as BisMags.
Anyway what this shows is that the barrel on the OP's AirWolf is a good one and THAT is what is really comforting. Nearly everything is down to the barrel.
