All of you using these smooth twist or ST-X barrel liners, is this normal? I had removed my ST-X liner from my new WC MK2 for cleaning and reinstalled, although it wasn't really that dirty... maybe 300 shots. But I got some new Air Arms 18gr in and wanted to test them with a clean liner but I was a bit perplexed at this:
I started off shooting at bull #1 at 50 yds and my shots were hitting down close to bull #5 where the mass of shots is circled. I removed the Tatsu/shroud adapter but the result was about the same. So I'm thinking maybe I borked something on the liner reinstall, perhaps not seated correctly or something, although it sounded fine when shooting. I removed the shroud, then the liner and reinstalled, loaded up some AA 16gr, aimed at the still bare #1 bullseye and the first shot landed to the right, where the small circle is. Ok, that's interesting. Made an adjustment left, fired a few more at #1 making a couple more small adjustments, then 8 shots to #2, 2 more clicks right and shot group #3, 4 and 6, 8 shots each. Sun broke over the treeline at 12 o'clock on group 6, that's my excuse and I'm sticking to it.
Is this normal? Something I have to deal with every time I remove/reinstall the barrel liner? I'm very methodical and careful on removing/reinstalling the liner, don't feel anything was amiss but I suppose it's possible. Thoughts? Normal, abnormal?
And a pic, cause she's so lovely:
cheers
