You can't get away from the fact that more moving mass has to equal more movement/recoil, but if you can delay the movement until the pellet has gone then who cares!

I think the point of the anti bounce mechanism is to slow down the acceleration at the point the piston changes direction, giving more time for the peak air pressure to flow purposefully... but if more of the % of the piston weight is inertia, all that will happen is the piston stalls earlier in the stroke, then is held a fraction longer by the arriving weight before reversing... But in that scenario maybe if would have been better to just have the weight added as static and the piston would stall later in the first place ?
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
