Bring enough gun. .17 is not enough gun.
It's also illegal to hunt deer in Oregon with the .17 I'm sure that is the case in other states as well.
Bad idea. If we are considering survival.......22 is far more common and available. Centerfire calibers can be reloaded.
With regard to compact, accurate small caliber firepower. I would prefer to have my Walther G22 over a .17 HMR revolver in a "survival scenario".
