Another beautiful and gratifying Crosman custom

[AirNGasman]

As is not unusual with these Crosman projects, this one has 'evolved' several times over the course of several years. The latest evolution is swapping to "The Exclusive" side-lever repeating breech from China (via Ebay), and an aftermarket stainless steel bull barrel machined for a P-Rod, slightly modified for the side-lever breech.

Much preliminary testing involved trying to eke out as many usable shots as possible from the HiPac HPA conversion gizmo; that being only 9-10 shots with an extreme spread of about 40 FPS from a 1750 PSI fill. Accuracy was not impressive; come to find out completely due to the wide ES.

Once I knocked the fill pressure back to 1600 PSI a five-shot string looked like this- Low= 515, Hi= 523, ES= 8, SD= 4, Average= 518 FPS/9.5 foot pounds. VIOLA!!! 

Now she averages .62" c-t-c five-shot groups at 25 yards, 1.34" c-t-c at 50 yards. 

So now I'm considering a custom (length) chamber-tube, in order to return many more shots per charge.

One thing about evolution...

IT NEVER ENDS! $$$!!!

Never ceased to be amazed by your obvious obsession with taking a pedestrian platform and ultimately turning it into an award winning gun. Doesn’t hurt that there’s a very accomplished shooter pulling the trigger on these terrific one offs.

Looking good now all you need to do is keep up the mods until you are happy with it. Cuz in the end that's all that really counts. Says the guy who put over a thousand dollars into one.

Many thanks KL. Hope all's well with you and your's, and that scope hit the spot for you.

I don't have the courage to investigate how much I've spent on 'personalized' Crosmans, Bio; but your post makes me feel a little better (I think). At least not so alone in my addiction.

You surely don't have to worry about ever being alone in yer addiction around here! We all love this stuff.
