Response to even better.

the closing force on the pump lever is 56 lbs! The other side of the equation is eliminating transfer port losses which can pretty easily be 1/3 of the firing chamber volume, because the firing chamber is so small, which means you can loose 1/3 of your pressure befor the air reaches the pellet. I think I've got my losses cut to about 1/5.
