Well, if you're 18 years old, have no debt, and have $14,500 (Canadian I'll assume, which is about $100 U.S.D. right?

**KIDDING**), then you're WAY ahead of the ball game compared to most people your age. If I were you, knowing what I know now, I'd resist the urge to blow that money on a super tricked out rifle and use it to invest in your future.
If I were you I'd buy the Savage you've been wanting, put decent glass on it, and take the rest of the money and use it smartly to benefit your future.
You could:
-Invest in the stock market for your retirement. Don't put it off, the earlier you start the harder that money can work to make you more money.
-Go to college.
-Put a down payment on your first home so you can move out of your folks place.
You've got lots of time to buy expensive guns later after you establish yourself. Spend the money you have now wisely.
