@centercut, polygonal barrel in my USFT agrees with your feeling. PHENOMENAL in the wind. I never posted the results anywhere as I did it before I posted on airgun forums, but I shot my 0.177 Brocock (standard LW rifling) against my USFT (polygonal LW rifling) on a bunch of different windy days, 10 shot groups around 53 yards (back fence at previous property). No hold-offs or timing for wind gusts, just held on same aim point.. Both guns in the high teens for FPE and both using the JSB 10.34gr. The center of the polygonal groups were always closer to aim point than the center of the groups from the standard rifling.
Edit: had another thought/data point. Bobby and Sandy are at or near the top of the heap in our monthly Extreme FTs. I believe that both of them are shooting Red Wolf HPs with polygonal barrels. Those barrels have also had Bobby's extremely skilled machining and optimizing (on that note, if somebody was to run some #s on how often a barrel touched by Bobby has been in the top 3 at EFT, it would be an eye opener). Now, they both are great shooters, dedicated enough to put in the practice time, and really know their guns, all of which are much bigger factors than having a poly barrel instead of a conventionally rifled barrel, BUT, those poly barrels are another piece of the whole package that has proven to be successful for them.
