Don't ignore .177 pellets for squirrels and rabbits! I can take my RWS Diana 48 or HW98K springers and a couple of clear plastic medicine bottles full of pellets in my pocket; a knife on my belt, a backpack full of necessaries, then disappear for a few days, a week or month in the woods and have a ball. I consider both survival rifles for small game.
Now for a viable option...if you wanted to take a PCP rifle....and a couple of clear plastic medicine bottles of pellets in your pocket, a knife on your belt, load your backpack with a couple dozen spare filled air bottles wrapped in bubble wrap to keep the rattling down, and pull a wagon with all your necessaries and an emergency high pressure hand pump... The two .22 pellet full medicine bottles will be twice as heavy as two pellet full plastic medicine bottles of .177 and volume 25% less in number so you may need 3 medicine bottles of .22's, bulging in the bottom of your pocket. The wagon will be kinda noisy and a pain in the you know what!
If I was to buddy with you on the extended woods walk...I volunteer to take the two plastic bottles of .177 pellets and 48 or 98k, knife and backpack full of necessaries......and you can take the 3 plastic bottles of .22 pellets, PCP rifle, knife and back pack full of backup air bottles and wagon full of your necessaries and emergency air pump. Sure won't be a quiet walk and listening to you complain after a few hours and may be the beginning of a miserable woods walk...maybe I'll walk a mile or two ahead, set up camp, build a fire, put a couple of rabbits and a squirrel on the spit, and wait for your grand entrance after dark.
