Bummer dude.
Do you have a high powered rifle to shoot long range?
Do you know the basics (ie: position, breathing, etc)?
If you're just beginning, look up an Appleseed event. You'll learn the basics of precision shooting out to 500 yards.
Only costs $80 for the weekend (less if you pick up a Gift Cert on sale til 12/31).

As a matter of fact there's one for Dec 28 -29.
