before you start changing sights - little info. You never said what your sight picture is.... Using the sights you have, the front bead should be at the very bottom of the rear sight "V" notch - not even with the top of the "V" ears. If you using the top of the "V" technique that would easily account for 8" high at 50 yard line. If this is the case then the fix is easy - use the rear sight correctly.
I hope this helps.
Good luck, medved404
Fifty some years ago, my dad taught me that when you run out of elevation adjustment, use "course" and "fine" front bead in the sight picture to further adjust the bullet strike. Using a "course" bead (where you see all of the bead through the rear sight) will always strike higher than using a "fine" bead (where you only see the top portion of the bead through the sights).
