Quoted:
I have a 7" .223 pistol and am having a bit of difficulity getting the sights zeroed.  It's likely to be mostly me and not the weapon that's causing the problem.

I'm using a 25m zero target.  The groups are fairly consistant but they seem to be all over the place; one time the group is high left, then low right, etc.

Can someone please tell me;

1.  If the actual point of impact on the target is high, should I turn the front sight to move the actual sight itself lower or higher?

2.  If the actual point of impact is too far left, should I turn the windage adjustment to move the actual sight itself to the left or the right?

3.  Should I be using the larger apature or the smaller one?

4.  What setting should I use on the elevation wheel on the rear sight?

Thanks !!!!!
