JJ, not a bolt, but given what I think about your adventuring....you might take a heavy look at the Marlin Papoose. Folks consider them a "grail" of sorts for SHTF survival type .22's. I don't know how much I agree...but they are kindof cool. http://www.marlinfirearms.com/firearms/selfloading/70pss.asp

I'd probably grab my CZ if I needed one rifle for long term survival.

Marlin 100...that sure is cool. Post some pics if you ever get a chance...would love to see it.
