All stayed around or under an inch. It's just that I could occasionally get 3/8" groups out of the Hornady ammo. If I stood on my head,, breathed heavily, shot left handed,, etc I could squeeze out more accuracy.
Seriously,, when things were "just right" it seemed that at 100 yds I could get some really tight groups. I may have to get it out,, when it clears up, & see if I can get some good groups & take a few pics,,,!
