That's a great article. I really enjoy reading when the author is clearly passionate about the subject. Long range shooting can certianly become addicitive (just ask my wife). I usually shoot eggs from 500 to 612yds at 740yds we shoot clay pigeons, and eggs, although eggs are very challenging at that range. In good conditions with a good rifle (and hand loads) shooting eggs at 500yds can be done with extremely high hit percentage. My buddy and I threw a video together (just for fun) here's the link...
(the over dramatic music is meant to be humorous).
At just over 600yds eggs can be hit with stunning regularity as well. 740yds is another story alltogether (due in part to difficult conditions and shooting a caliber (308 win) that has poor wind bucking and ballistics), that's why we step it up to clay pigeons, when you spend hours handloading missing hurts! We've got steel set up at 740 also it's not very large I'd say 10"x12" great size to practice the "cold bore shot" and print some groups to ensure rifle/ammuntion accuracy. Here's a few pics
also have pics posted of where we're shooting to here
