Nice. At about 9lbs, yes, it is a beast of a springer.
I would reccomend using heavier pellets - at +/- 1000fps, you'll get great hitting power, but your accuracy will suffer at longer ranges. Experiment with something like JSB Exact Jumbo (18ish grains) or Exact Monster (25ish grains). These should bring you down to somewhere in the 800 - 900 pfs average, which is a sweet spot for accuracy and hitting power.
Your results may vary, and like PBs, springers are pellet sensative, but if you're interested in being reliable at +/- 100 yards, you'll quickly see that speeds like 1000fps creates too many wanderers.
