I read it several years ago, but I have to be honest, I read too much of that stuff to remember what I've specifically picked up in one book versus another. It's sitting on the bookshelf above my reloading bench, maybe this is a good motivator to pull it back down and refresh on it.
I've done tons of reading on "snipers" and long range shooting - not because I'm some Hathcock wannabe, but because I have always been drawn to long range hunting and target shooting, which goes hand in hand with military sniping, and the evolution of snipers in our military history is really an interesting story in itself.
The problem, if there is one, with this type of book is that you'll find that unless you're a military sniper, or using their equipment, much of the information is specialized to their equipment, so it's not always accurate and/or applicable for what we might find ourselves shooting in the field. For example - I can't recall if this is in "Ultimate Sniper" or in one of the military sniper/sharpshooter/LLRP/Etc manuals, but there's a formula for wind drift - (range in 100yrds x wind speed in mph) / 15 = MOA windage. It's actually a decent rule of thumb if you're shooting a 308win, as it tends to be accurate enough to get "minute of enemy," but when you're running a 204 Ruger at 4000fps, or a 7mm mag at 3200fps with a higher BC bullet, OR a 30-30 with a much slower bullet, it really doesn't apply.
But just looking at my copy, I have document tabs sticking out all over the book as bookmarks, so apparently I found it interesting and valuable enough that I wanted to be able to go back and revisit certain references.
