Do you have Natl' Match sights or normal sights?
According to Marine Corps rifle doctrine....
Battle sights is your 300 yard (prone) rapid fire setting, minus three clicks of elevation.
If you don't shoot High Power rifle, this may not help you a lot. (But you should. So there!)
The other option is to sight in so as to be registering four inches high at 100 yards. That should put you on a 12x18 inch rectange out to about 250 yards. Past 250, aim for the top edge of target... that extends out to about 350 yards.
350 yards off hand is a fair piece to shoot.
Further than that, you should prepare a sighting chart for your buttstock.

The quickest way to do it is the following, in these steps:
1) Buy a big ammocan. Big tupperware containers work well also.
2) Put hundreds of rounds of 7.62 NATO cartridges on strippers and put them in the can or tupperware.
3) Go to range with about 5 20-rd clips, M14, and ammo.
4) Strip off shells into mags until full and lay them to your left (for right-handed shooters).
5) Insert first clip, pull back action.
6) Aim somewhere down range.
7) Budadadadaaaadadadadadadaada!!!
8) Miss? Insert another mag and try again.
9) Budadadadadaadadadadaaddaada!!!
10) Miss? Insert another mag and try again.
11) Budadadadadaadadadadaaddaada!!!
etc...
With hundreds of rounds down range, you gotta hit it sometime....

Here's the fastest method. Assuming its SHTF and you find an M1A lying on the ground as the jubilant soccer fans rape, pillage and plunder your home town. It's time to defend the home front. Assuming you don't have time to test it at the range, dial the rear sight elevation down to bottom. Then come up twelve clicks. Check the windage setting is in the middle of the serrations on the receiver. You should now have a 250 meter zero. That is point blank range (within 5" high or low of point of aim) out to 300 yards.
I have sighted in at least seven M1As and they have all had 100 meter zeros at eight clicks from bottom and a 250 meter zero at either twelve or thirteen clicks from bottom. The windage setting is always three clicks or less from center. FWIW

In the Army manual that comes with your M1A it should state (if I remember it right) exactly what different said. Crank the sight all the way in, 8 clicks up for 100m, 13 for 300m. All of mine fit this mold.

Is the elevation screw loose? sometimes that can make the sights feel "mushy" when adjusting them (but don't oertighten it either)?
Basically I do it the same way as espoused by different and the others I bottom it out until the last full click-sometimes it will go a bit further but go from the full click then up 8, sometimes as much as 12 and then center the windage. Then shoot it. If you are more than a few windage clicks off (assuming the wind is not a factor) I loosen the set screw on the front sight and slide the front sight over to compensate until it is on, then I mark a small thin vertical line on the front sight with nail polish (to visually make sure it does not move once zeroed). And the ball park formula I use for elevation past 100m is 1 click per hundred meters (sight is set in meters if memory serves me right) +2 clicks at 2, +3 at 3 etc. Reading the wind is your problem, I have my own ways of reading it.
