Made the first trip out to the range with my new shilen tube. Rifle is a savage F-class dual port timed and trued by SSS. Scope is a Sightron SIII 10-50. Bullets were Berger 105gr hybrid jammed .015". First groups look pretty good. It was gusty out today but all groups averaged right at .52". I expect that to decrease once I get a good load worked up.
