grrr....i need to put mine back together (it has not been fired yet) once we thread the barrel (waiting til a laundry list of other machining projects are done first) and i have the new internals in (some are on order). The gun will be mostly volquartsen inside, a delrin recoil buffer rod (to improve the overall action suppression) and various other tricks here and there. it will complete my ruger .22 collection (coupled to the threaded bull barrel stainless Mark II and the VERY unique 77/22s Richard and I are building based around some very special barrels and the Aguila SSS round). I got obsessed with stabilizing the Aguila bullets in a suppressed weapon about a year ago. I'm finally getting around to actually doing the project. four of these barrels are on order to be made and I will be one happy little camper when i can hear nothing but the firing pin hitting the rim and the SLAP of the 60 grain projectile slamming into the noggin of some unsuspecting groundhog.
