A lot of ranges and matches in your area to get you started. I would establish muzzle velocity on your chosen rifle and load you will use. Pick up an inexpensive or FREE program to calculate your trajectory. Strelok, Hornady, JBM to name a few.

Rear bag is a must. You can make one if you search for the different types.
Also check to make sure your scope tracks elevation or know the correction factor. (Hunting scopes might not be able to dial with markings, only zero and hold over).
