Good deal.The Beeman FTS is 8.64gr. The Gamo Rocket is rated at 1300fps and that has got to be with PBA ammo that should NEVER be shot in this rifle. I would suggest, since this is a magnum springer, getting heavier ammo. I have had good luck with Crosman Premiere brown box 10.5gr rounds. But something closer to 10gr might improve your accuracy and as I said before, also give more punch down range.http://www.pyramydair.com/s/p/Crosman_Premier_Heavy_177_Cal_10_5_Grains_Domed_1250ct/154Rather than invest in such a large box, send me a pm with your mailing address and I can drop you a few in the mail to test with. I think you will see a big difference in performance, if the gun likes that diet.
This hobby may delay my return to racing 1/8 rc offroad.
