Let me know how that goes. Besides, Deagle is bigger and easy to find.
To the threadstarter: If you want to start off inexpensive and still go out pretty far, you can get into smaller, hotter rounds for far less $$$
A Savage in .17HMR can be had for under $300 new. I paid $100 for mine new on clearance.
You could also find something in 22-250
After that, you just need optics, which again, is where you will spend most of your money.
If you decide you want a larger caliber, then stick with .308
For something better out of the box, go Savage
For something with a bigger aftermarket, go Remington 700
