So I had a chance to start shooting some groups with the 'plain' LW barrel tonight at 75 yards. I can confirm that the barrel simply isn't as accurate as the LW Polygon barrel. There were times when I would be shooting a few shots, thinking 'that's going to be a pretty decent group' and then, all of a sudden, one of the pellets would fly off left, right, high, low. At first I thought it was the wind, but it did the same thing once the wind was completely calm. I thought it may be my eye position, but I very consciously tried to keep things very consistent (granted, sometimes I would slip up and look at the target, rather than my reticle-so some of them were my fault, no doubt).
Stay tuned and I'll edit this post with a couple photos. I'm going to sit and relax with my wife a little bit now though.
Oh, and BTW: we have a new member of the RAW family! I was able to find someone interested in selling the exact setup he wanted (.25 cal, polygon barrel, grey charcoal laminate LRT stock, with a single shot adapter, Picitinney rail, and carbon bottle)-all just 2.5 months old! He received it in December, 2017. They struck a deal, he paid and is now waiting for the gun to arrive! I'm so happy for him: AZ just told him a day or two ago that Martin just said his gun order would be another 20 weeks from this week (after waiting for 8 weeks)! He was really upset about it-so it turned out to be a real blessing!
