shady, I did some 35 - 40 yards shooting on a tree yesterday on a very calm day. Using a leapers 3-9 X50 AO scope I thought I lost the 2nd and 3rd shot since I can't see where they landed. When I checked it with a higher mag scope (uninstalled, I just used it as a handyman's monocular) they are all touching each other. Fired 5 more shots and all are still touching each other using JSB Exacts 4.52mm 8.4grains pellet. At 10 yards the RWS superdomes works better for me but I noticed that at longer yardages the JSB's performs better. Maybe the JSB's have better ballistic characteristics at longer distances. Sorry, no pics of the target. I was shooting inclined at about 30 degress so that would make the height of the POI's from where I shoot to be about 18 - 22 feet (just an estimate). Can't focus the cheap digital camera I have at such height.
The barrel has been re-crowned and polished as well so that helped a lot on the accuracy department at long distance shooting. Play around with your B26 and try using a stiffer spring. You might be surprised that it might give you the same results as mine.
Question: "Are you still using the tube with a scratch inside or were you able to get a new one?" Was it you or another member who had that problem with his B26? Thanks.
