I love these things! I was introduced to them in Alaska by bush pilots. They are light, they float, and pretty cheap. As far as reliability goes, reviews say they jam a lot. I had experienced this also, I bought some good Remington gun lubricant and the issue has not arisen since. My thoughts, the .22LR is the perfect round. A person can hold a hundred in his pocket! With a well placed shot in a survival situation, I am positive you can take down larger game.
