I have 100ish dollars to spend on a gun/anything else hunting related?

Well... uhm... I would honestly recommend a tomahawk to you over a .22 just because you can only hunt very small game with it... however.. you cannot even afford a tomahawk. I suggest asking for a bigger allowance, and maybe getting a gerber savings account and maybe wait a few years and get a real gun

Could get more ammo (can never have too much), hunting clothes, new knives, gun slings, recoil pad if needed, more gun cleaning lubricant.

EDIT: You can't buy a Mosin-Nagant for less than $100. You add tax to it and its over $100.

Mosin Nagant M91/30

Vintage WWII era bolt-action rifle. Shoots a Russian 7.62x54r which is cheap if you buy surplus ammo. You can find them for $100 and they usually come with a bayonet!

Have you ever seen Enemy At The Gates?

Look at what you already have for firearms and at this point in time put your money into ammo. Prices are going to inflate quick and high shortly.

I would find a job and earn more before go shopping.

But if you must, check Rossi http://www.rossiusa.com/ they are not the best, but they got better than they were

yeah, I'd save it until you have more money, unless there's something you need for hunting.

I would buy a nice range finder.
