Buy once cry once. Save and buy the rifle you want and know you will be happy with. Don't buy strictly on price point. If what you really want is out of your price range look at used rifles, local on line ads, shooting forums like this one, you just never know what you might find if you take a look. Think of it as a life long investment. I bought my first big game rifle when I was your age, a Rem Model 7 in 7mm-08, I've gone through a considerable number of rifles since but guess what, that old Model 7 is still in my collection. As for caliber I highly recommend something in the 6.5/.264 bore. Maybe a .260 if you are looking for a short action or a 6.5x55 Swede for a long action. Neither give much of anything up to the '06 with 140grn bullets and recoil is negligible. Unless you plan on hunting elk or bigger critters you don't need to beat yourself up with recoil to kill deer. Get something that will do the job and not kick you out from under your hair. In the long run you will become a better shot cuz you'll shoot more and not develop a flinch or other bad habit.
