Joe, that 800fps in .177 is probably pretty close.

Response to HW35

In factory form, my HW35 "K" was shooting the 7.33gr AA Falcons at 811fps and the 7.87gr AA Express at 789fps. But it started getting too twangy so I put in a Maccari Ultra Pro MKII kit and a Vulcan SS piston seal. The seal is a little too tight but it's still getting 770fps with the Falcons and 758fps with the Express.
