I've played/play with a multitude of things that go "bang" and noone serious about low ES can say that precompressed trumps a piston,under the assumption that they have a chronograph. Guilty of a PACT Pro here.

RWS will often run SD's in the mid single digits,while a high zoot Feinwerkbau will delve in the nothings on the average. PCP's require being topped incessantly to hang,which negates any perceived "advantage".

When it's time to make blood spill like a river and stealth is a requisite(less a can),then I'm in Marlin 39 Mode,stoked with 31 rounds of CB's and a Leupie scope wearing an ele turret.

Tournament Crow Hunting being that fixation,on the average.
