Sight Picture Question

[iiibbb]

Ok, so I don't have my scope yet and I'm trying to figure out the sight picture...

It's a .308, 24 inch stock barrel.  I'm lining the sights up so that the post is between the little grove, but the white dot is not in the grove, I assume we're looking for a little daylight between the post and you can't get that if the ball goes in the cup.  I'm putting the target just above the right dot.  I seem to be shooting high.  I guess the ball goes in the cup... but it seems a little hard to line it up this way.  

Any suggestions?

I always line up iron sights so that the front sight sits perfectly horizontal with the rear aiming references points, whether it be a U or two more dots.  I then line the front bead up with 6 o'clock on my target and let her eat.  This is the way I was taught with pistols and iron sighted rifles etc...

The problem is it's quite unclear what the rear reference point is.  The rear blade is a U shape with a shallow rectangle grove... at the center of the rectangle is an even smaller U grove.  If you put the bead in the U it's hard to get your cheek down that far, and it's hard to center the post.  If you let the post sit in the groove and the bead sits in the middle of the rectangle, it definitely shoots a little high.

I dunno.  I'm putting a scope on it next week, but I wouldn't mind understanding the iron sights better.  This is definitely among the worst I've used.

However... the groups will be pretty darn good.  The potential of this rifle is apparent.
