I want to thank KWK for a tip he gave on another thread. He mentioned that bubble tubes worked well as homemade piston liners. I ordered the same ones he recommended and tried them today. I'm really happy with them so far. I cut up one of these bubble tubes and made a piston liner. They were easier to use than cutting up plastic drink bottles or the ptfe sheets I was rolling. My 22 HW95 had a little bit of twang left in it and now it's completely gone. I'll have to order more bubbles for future guns. This was a great tip. Thank you KWK.
Same gun another issue. I've been struggling with POI shifts with this 22 HW95 at 50 yards. While apart today I noticed evidence of piston seal rotation. For good measure I replaced the piston seal with a fresh Vortek seal. Hopefully my POI will be more consistent. I scrubbed and polished the barrel last week and lost a bit of power and now its a bit slower yet. New seals are tight. It's at 660-670 now. I'd like to see it back to 700 after the seal breaks in and the barrel completely seasons.
