In all seriousness though, what were you shooting and how far away were you really? That's a pretty tight group.
Factory Tikka T1x barrel - .22lr - KRG Bravo Chassis - Vortex Strike Eagle 5-25 x 56 - Harris Bi-pod, from a bench - shooting Lapua Center-X and Eley Match - that group specifically was Lapua @ 50 yards
I'm a newbie, trying to get my technique dialed in.
