Tab I'm surprised you did not provide the link from one of your previous posts.
Here it is.
http://www.archive.org/details/Rifle_Marksmanship_with_the_M1_RifleThat the rifle is an M1 does not matter, it all starts with the fundamentals, which apply to any firearm including the long gun.
Good position, sight alignment, trigger control, repeatability, understanding the conditions and how to read the wind and mirage and adjust accordingly. This series of films go's a long way toward that understanding. NRA rifle targets are 2 minutes of angle for the 10 ring, and 1 moa for the X. So with iron sights, 2 moa is hitting the good stuff at any given range, yes that is a 20" circle at 1,000 yards. The 9 ring is 3moa, so if you can keep them all in the 9, with a few 10's thrown in, that is above 90% possible score.

That is expert.

Poorsoul, you did not mention if you were going to be shooting optics or irons or both. Learn your sight adjustment increments for both, it's pretty easy, for irons, but sometimes you need a calculator for optics if you have 1/4 to 1/8 minute clicks and your going for extended range. By the way, NRA highpower rifle considers 800 yards, medium range.
