Thanks Chuck, the down side is now that the compression side losses are being eliminated

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.
