I have a Ron Hoehn tuner on my Suhl 22RF target rifle. The tuner is made by Lynwood Harrel of powder measure fame, and then sent to Ron Hoehn for final reaming of the hole to fit your barrel. You, I, need to send measurements to Ron so he can ream accordingly.
It works!!!
I have some pretty accurate 22 RF target rifles, but I can deliver 5 shot, 50 yard targets that measure in the teens, or better, with the Suhl w/tuner.
