Did you try Dsbfabrication tuner? There is no difference tuning a Fclass barrel and any other barrel. I was serious you could source a Teflon lined nut and use that as a tuner.Anyone have any experience with Erik's tuners on a short range 30br benchrest rifle?
They seem to be more popular in the fclass group, but was wondering how they would work on a benchrest gun as they seem to be one of the few i can get in Canada.
Thanks
