Have you seen this online tutorial?
I was given a youtube online tutorial.
Go to youtube and type in tiborasaurasrex sniper 101
This guy has at least 66 videos about Long Range Shooting, each avg. about 25 min. He explains things very simple even an old fart like me can understand. It covers everything from picking the right firearm/caliber to optics, barrel harmonicas etc etc. It is all set up starting with part 1 and goes clear up to part 66 (last time I checked) I found it very enlighting. He starts a little slow but.then relaxes and is a very good speaker/instructor. If you haven't seen him then you might want to check it out.
