Shot a 30-30 this evening with an old japan 4 power Tasso on it and seemed 2.5” - 3” was the average size groups using Hornady FTX factory ammo at 100 yds . Thought it would have been better . Had some othe caliber levers there that shot better .
Thinking about trying better glass . Parallax maybe ? Ran out of time will give that a look tomorrow .
