Does anyone have any experience of a T Bolt in 0.17, Is it accurate compared to a CZ, I'm looking to aquire a semi auto 0.22 rimfire and a 0.17 either Mach2 or HMR, how does the Remington 597 stack up against the Ruger 10/22. The Semi auto will be the main lamping gun with the 0.17 being used as and when the range will be testing the 0.22 Regards Dave
