Crossman 2240 fitted steel breech, power spring, power adjuster etc. still only making 3.1 ft lbs over the chrony. Tried tightening the adjuster but you just get to the point where the hammer spring will not cock! after several strings powerlet went thud and assumed empty but strangely there was no drop off of power towards this point. I've opened up to change the Co2 and I can't get the empty one out! now I've tried hitting the end with a rubble mallet I'm a little bit wary of drilling into the Co2 pellet as there will be swarf going into places that don't want it. Any ideas folks?
