Finally got the PWS variant to 100% operation--- required barrel shims totalling .006-.007" for the Fedderson barrel, replaced the PWS firing pin, spring and extractor with Volquartsen replacement parts (what they recommend to fix PWS problems with light strikes and extraction issues). Shimming of barrel to point where there is just a little bit of feel on the bolt cam when you overcenter it to close, less than a pound of force when measured with a trigger gauge.
Put 257 rounds through it with the 1st 157 being leftover various rounds from many years that had accumulated in the bottom of the range bag. Really it was a real mixture of HV, SV, thunderturds, Federal, Winchester, Eley, Sk, CCI, Aguila and what not. I was just trying to establish functional reliability of the action. The good news is the volquartsen parts and additional barrel shimming took it from about 40% reliability to 100% for feeding, ignition and extraction. I did suffer about 22 "harder than normal to feed/close bolt" with the off brands, noticeably the federal and remington crap.
I then switched over to 100 rounds of SK+ and ALL feeding issues went away and surprise surprise, accuracy was a lot better too. The lube SK uses really made a difference for this action. Rifle is just as quiet as a bolt action with the suppressor, this is what I wanted from the beginning.
Targets 1-5 and above sighters were scope zero and functional testing, did notice that any HV rounds pulled high left of POA. Yardage 25 from the bench with bag, winds variable 0-8 MPH out of 7-8 oclock. Targets 11-15 were all SK+ ammo. Ignore Target 18 as it was standing offhand unsupported, just wanted to see how the rifle balanced in offhand shooting.
However I have decided to stick with my other .22's at this point and pare down some of my stuff so this receiver is going on the "for sale" pile. I'm glad I finally got it sorted out, but the Toggle action isnt for me, I'd rather have a semi-auto or true bolt action. I'll make a fellow SH member a hell of deal for the action with the PWS trigger pack and volquartsen parts.
