I have a 10/22 converted over to shoot this round. My limited testing so far has revealed that 50 yard 3/4" groups with both CCI and Hornady ammo are very realistic with some groups being considerably better and a few being around the 1" mark (5 shot groups fired from a stable platform). In comparing this rifle and round with a 10/22 I built in 22lr, it doesn't shoot quite as well as my 22lr shooting Wolf MT ammo. It is however completely capable of being an excellent squirell or small game rifle, plinker, or just a toy. If you're looking to get supersmall benchrest type groups, I'd probably stick with the 22lr because of the upgraded ammo available ie Eley, Lapua, etc.
