Discovery Hammer Bounce / Debouncer

I have done several mods to my Discovery including a Magnum Airpower power adjuster, Challenger hammer and heavier hammer spring and have arrived at a nice compromise between power and shot count (21 shots within 4.1% of ES at 30 FPE using JSB 18.13 pellets). I do notice with this set up however that there is a fair amount of movement in the gun caused by the hammer release - enough movement to interfere when I am trying to do precision shooting. Is this caused by hammer bounce rather than just the hammer force and can I do anything about it that will not compromise the power level? Would the Freeflight Hammer Debounce kit help to reduce the 'recoil' from the hammer?

BTW I have the striker on the Challenger hammer recessed 1/16 inch from the hammer surface. Is this an optimal setting for performance / efficiency?
