Long Range Shooting for RBscorpionking
0. Be sure you have convenient access to a long distance range.
Maybe this goes without saying, but multi-hour drives get to be a drag, fast.
1. Buy a Shot Marker target (a single shooter system is all you need).
At 600+ yards, it is impossible to see you hits on the target. Shot Marker removes that limitation.
It also means you can practice solo, if a buddy cannot go.
Shot Marker tells you your velocity at the target.
2. If you are going to do this, buy the best freakin' rifle you possibly afford, paying special attention getting a great barrel (Krieger,... or whatever) properly chambered and installed.
3. Make good ammo.
Load test at short range but prove it at 600, then 800-1,000 yards.
You have to stay supersonic (with margin) all the way to the target (short-barreled 308's beware).
4. Go have some fun!
You will learn more on one windy day than "a month" of calm Sundays.
P.S. - I could be completely wrong about all of the above, except item 4.
