This article Long Range Shooting & Hunting has been on Daniel Lilja's site for a number of years. Even though it is somewhat out of date, I'm sure there is a lot of usefull info for you there.
Don't write off the "girly guns and tournment paper punching" shooters. Look at them this way. A lot of the innovations that we take for granted with respect to our automobiles, such as tubeless tires, electronic ignition, rack and pinion steering, ect. were developed on the race track. Same thing applies to rifles. Someone a while back, I believe it was with a 6.5/.284, set a new world record, 5 shot group at 1000 yards of 1.99", if I remember right. I am sure the group was under 2". That achievement didn't come easy. It represents an amazing combination of a lot of skill, hard work, painstaking preparation, and top notch equipment, properly set up.
Myself, I'm getting all the components together for a 1000 yard BR rifle. I am going to send it all to Randy at Action Gun Works to build it. I've already got a couple rifles that shoot acceptable enough to enter in the matches. I am going to start competing next year against "girly rifles" like the one shown below. My strategy is I should be able to win because his action is painted with purple PTFE.
