RE: never hunted
If you know anyone who has guns, ask to go with them the next time they go shooting. The only thing that will make you a good shooter is experience. If you don't know anyone who own guns, get hooked up with some guys from the local NRA, I'm sure they'd be more than happy to teach you how to shoot. Once you've learned who to shoot, set yourself a budget and go look for a good deal on a rifle. A 30-06 would be a great rifle for you if you're not sure of what caliber to get. After you buy a rifle you're going to need to buy scope rings (if not included), sling swivels, a sling, a scope, and some ammo. One of the most important things to purchase is a survival pack and a compass. You'll learn more about that in hunter's safety. As far as clothing goes, you're going to want to get some long underwear, gloves, a warm hat, some sort of blaze orange vest, and some hiking boots or packs. You don't really need to buy camoflague clothing if you don't have the money. Drab colored garmets (tan, green, brown, ect) work just fine. Lastly, you'll want to buy some binoculars (don't need to be anything fancy), a field dressing knife, a knife sharpener, and a bone saw. Have fun and good luck!
