forget all that rubbish.
go and buy a nice mechanical cocker for next to nothing and shoot fools all day long.
who needs 17 + bps in the forest???
you will get 8-10 bps out of a mech cocker easily, you won't need to buy a stupidly priced loader to keep up and batteries will never run out.
get a decent barrel and have fun!! if you are playing rec ball and presumably paying silly money for paint why shoot it all quickly with an angel or whatever?? get your cocker use half the paint and have twice the fun!!
