So a big thank you to Screwwork for the trade! This was a black 1377 yesterday and is now converted to .22 cal carbine for yard pesting. It has a home made power adjuster with a spacer/guide and a Discovery hammer spring, a highly polished hammer and trigger group with washers to eliminate side to side movement and a lightened sear spring with guided creating a crisp repeatable trigger,.165 Ice maker tube T.P. a super pumper forearm, steel breech kit, extended magnetic probe,homemade fiber optic front sight, LPA rear sight, BKL mounts holding a 30mm Leapers/UTG 3-12x44 S.W.A.T. Scope w/ etched glass half mil-dot reticle & the EZ tap Illumination with a 110 lumen light and laser with quick release..and a shade tree camo job too. It seems to prefer the 15.89gr JSB Exacts with very tight 20yd groups dime sized, and does well with the Metal Mags too. Not tossing a ton of energy but with this kind of precision it is plenty for 10-30yd squirrel and rabbit eradication and no more CO2 to buy. I gotta say I'm loving this little shooter. gonna throw on my Orion camera mount and do a bit of pesting... Here is the data for two 10 shot strings:

This is enough juice to do yard work for me but I wanna go 14 inch barrel to allow for my TKO brake, and I am very interested in the flat top piston and valve as well, but I am loving the freedom of this little pumper!
