I'm thinking any of the better bolt action 22's would easily last a couple lifetimes with any care at all.
In the 70's i use to go to "Jacks gunshop" that Jack had in his basement. This guy was VERY knowledgable and i really trusted his opinion. One day i walked into Jacks shop and announced i was moving to Alaska, and i wanted the BEST most reliable 22 money could buy! I told Jack that i wanted something that was VERY accurate and would last me the rest of my life!
Jack went over and pulled a beautiful slim trim bolt action 22 off the rack, saying it's what HE would buy for the job i described to him!
I bought that Anschutz 22 for $95 or 96.00 and that was in the early 70's. Since then, it's been beat on in so many ways you couldn't imagine, from dropped, ran over, steped on, in fact it even was in my house when my house burned down!!
It's been, from hunting in the desert heat, to waaaaaaay below zero temps on Ptarmigan hunts in the mountains in Alaska. I took it on hunts in the temporate rain forest for weeks at a time... AND all along the way, it's shot a truck load of ammo!!
It's now on it's second stock as the origional one got busted off it! That's the only repair it's had...
I put the 10x scope on it to see if it's still accurate, it still shoots cheapo ammo just fine, and that's pretty much all i've ever fed it.
I've depended on it to feed me many times, and it STILL works perfectly, just like the day i bought it.
I'm betting it will outlast me, and a couple more family members too!
How's that for rugged???
