I'm trying to decide on what Air Gun to purchase. I'm not opposed to waiting a year or so and saving my money to get something good, but it has to fit my needs. My major need is that it needs to work in any environment for any amount of time. I don't know if PCP will work for that. I can't be bringing in multiple tanks just for a 3 day trip, so I'd need a way to have access to air during the time. It also needs to last pretty much a life time. I'd be cleaning it and packing spare parts as well. It'd need to take at least a squirrel but at most, a deer? I like the idea of being able to take something big with it. If it's not obvious, this will be used for hunting. To take a pig would be nice too. The reason for owning this would be to hunt and keep my family fed in a disaster. Another thing I need is the ammo to be easy to pack. A .22 can easily have 500 rounds in my pocket at any time. I like that. I'd love to be able to change ammo sizes. Having a bullpup that takes .357 but can also take a .22 round with an adapter or something, I'd like that. Give me some suggestions please, I'll answer any other questions you may have. Can be break barrel, PCP (assuming there's a way to refuel the air at a base camp), or even hand cranked from the bottom. It needs to take a squirrel at the very least. Thank you.
