I have been slapping steel (and p-dogs) at long range for many years. My experience has taught me that gear can be bought, matching rifle to ammo is not too difficult, but experience has to be earned.
FWIW, coming up with the proper (repeatable and reliable) dope is the toughest part of all. After you have the techniques nailed, the real key to success is developing a deep rooted understanding of the environmental variables and how to develop a firing solution for those variables. Pulling the trigger becomes the easy part. Master the basics first out to 1000 yds,then worry about the little things, like spin drift.
FWIW, I have my own 1500 yard range and my own steel targets in sizes from 6 inch circles to full size USPSA metric targets. Shifting winds and mirage are the long range shooter's nemisis.
