50 yards Anschutz 1710 HB, XLR chassis 23" barrel, 65 degrees F 5300' alt. inside. Weaver 36x fixed scope. Barrel Tuner install and test for best nodes. Made the tuner out of 6061 aluminum with 1.375 x 20 threading, total weight almost 13oz. Was a fun lathe project.
Put a barrel tuner on the rifle, needed to find a good node setting. Take a look at Varmint Al's excellent 22 tuner page for more info on using tuners: http://www.varmintal.com/a22lr.htm Great for a bench gun, maybe not so much for other matches.
Started here at a setting of zero and worked up to .650" in .025" increments. Promising groups at .150" and .550" led to further testing around those values, with .540" being the eventual winner after shooting nearly a full brick of Center-X over 3 hours. Just showing the first and final targets to save lot of in-between targets. It was interesting to see how the tuner changes moved the groups around the aim point and opened or closed them up.
Starting target for tune at zero:
final tune setting testing page with an outstanding .072" group at .540" tuner setting for an average of .131"! :
