Well... Mr. Bentz offered to sell me a sight, but did not recommend a height.  He just told me to let him know what height I need the sight to be.  I haven't got a clue!  I guess I need to know what height I need to be able to use the 600 yard setting on the rear sight for 1000 yards.  That way, I can go up or down to fine tune things!  Does anyone know?

Sorry if I sound like I'm in over my head, and haven't got a clue.  The truth is... I'm in over my head, and I haven't got a clue!!!  I really want to get this right the first time, and learn!  I'm just asking for help...

Addendum:  I just noticed Para's recommendations on blade heights.  Pardon my ignorance, but I'm not quite sure which height I need, so if someone can please explain to help me understand.  Thanks.
