Re: PCP needs cleaning
Check out "Gateway To Airguns" for all of your air gun questions. Lots of helpful and knowledgeable air gunners over there.
Winchester Model 70 Black Shadow in 300 Win Mag, all factory, shooting Remington Core-Lokt 180 PSP factory rounds. Shoots too good to try and "fix" it. Multiple one shot kills to 400+/- yards and one kill at 815 yards.
Winchester Model 70 XTR in 264 Win Mag with Nikon 4.5x14SF BDC running HSM ammo loaded with 140 Grain Bergers. Antelope killer!
Someday, a APS Raptor LRSS in 338 AX. Time to step up my game. Ordered 10/2011 and still waiting!
