Thanks. I did a search as suggested and found some great ideas in regards to iron sights and zero. One forum was about individual owners and the amount of clicks from the bottom up on the rear sight to obtain certain distances ie 8up = 100yds,10 for 200 and 27up from btm. for 600 yrds. I'l be writing those down when I get to the range. Also the idea of adding extra clicks for a 6oclock hold ie +3more at 200yrds,+2more for 300yds. Anybody know their clicks? Then the idea of zeroing POA and POI at 25 will get you on paper at 200yds. Any of this sound right? Or should I try again? Thanks
