Flatlander, I have observed same as you, ammo with great accuracy opening up at distance. Also note a different tuner setting will usually tighten it up at 100 and that setting will usually do ok at 200. Realize you are shooting PRS-NRL style matches where a tuner might be impractical, but it could conceivably lessen the strain of the ammo chase for (accurate +low ES + $$$$) Intend to see if there’s anything in it for 300-400, etc when weather permits. Greatly interested in the Vudoos. Plenty very solid guys having real world excellent results. Seymour
I understand a tuner would be in order if I were shooting 22RF BR for groups at set distances, but it's not a practical solution when our matches are at distances from 25yds on out past 300. And besides, I usually shoot matches suppressed, so that rules a tuner out.
