Just picked up a Ruger 77 in 17 Mach 2 and am greatly impressed by the accuracy of this little round. Now looking to get a semi-auto...either a Marlin 717M2, complete Volquartsen rifle or convert a 10/22.
Definitely not a plinking round alright. At two to six times the cost of .22LR it becomes pretty expensive to perforate cans and paper. Still half the cost of HMR though, which is why I went with the smaller round.
