Zero Distance

[alelks]

I'm surprised this hasn't been discussed yet.  Personally I'm planning on zeroing my Larue with the EOTech at 200 yards (darn hard getting use to using yards rather than meters).  The reasoning is, that distance will pretty much give my my flattest trajectory at a decent distance for the sight being used.

Here are some specs as an example of zeroing at 300 yards (not the 200 I'm shooting for but it gives you some good data none the less):

(Bullet Path in Inches at Zero Range of 300 yards (100, 200, 300, 400, 500)

5.56mm NATO (63 grain @ 3200 FPS): +3.68, +4.58, 0.00, -11.81, -33.33

7.62 NATO (168 grain @ 2700 FPS): +4.79, +5.58, 0.00, -13.02, -34.75

I'm curious as to what everyone else is zeroing their weapon at using like or similar sights.

I did my DPMS at 200 yards as well.

I set my PointBlankZero with 6" impact area:

165 gr. Fusion, 2700 fps = 231 yds

100 yds = +3.5"

300 yds = -5.9"
