Good advise from ShooterXD. I own both calibers and as i see it theres a tool for every job, a moderated .22 sounds like a mouse fart compared to a HMR in the field. i would say buy a CZ 452 in .22 stick a SAK mod on it, 200+ rounds of CCI subs and go enjoy it. .17 HMR is a great round turning crows to feathers or knocking rabbits over at 200 yards. Enjoy the .22 LR first you will be supprised what it can do once you have master the trajectory. just another thing bud, i wouldnt buy a second hand HMR unless you no the rifle or you can try it first.
