Nice upgrade - Shaw Ruger 10/22 22 LR Threaded Rifle Barrel

I've put about 150 rounds through it so far. Ammo quality makes a big difference in group sizes. Thunderbolt was least accurate. CCI std velocity target 1.2" @ 50yds (nine 5 shot groups). Eley Club .622" @ 50 yds (four 5 shot groups). Eley match .726 @ 50 yds (four 5 shot groups). Ignored the first 5 shot group after cleaning the bore when switching ammo. Barrel was a slip fit in the factory Ruger receiver. Installed in a hogue overmolded thumbhole stock made for a .920" barrel diameter. Also upgraded the trigger while I had it apart.
