Thanks for the info! I plan on shooting up the rest of the power belts just to get in some range practice/get used to the gunand then switching to a better bullet for next fall.
I plan on getting several bullets and playing around with bullet/grain combos to find the best one for me, I was just worried I was overpowering my gun w/ 150 pellets of 777.
So far just getting my feet wet has been a blast

Even though it is more expensive I believe I'll stick to pellets for now to try and keep things simple! Any other tips welcome,
Thanks,
Matt
