Zeroing distance for Irons/RDS

[Kaiser.Shooter]

We actually run a 50/200 zero now.

The 300yrd zero gives you a smaller cone of deviation, but puts your rounds at the knees at 400.

The result of that is at 400 yards you have a hold over that blocks target image with iron sights.

The 50/200 opens up the cone of deviation to about 9 inches (nearly triple the 300 yrd), but is still combat effective, and puts 400 center hold hits in the groin area. That means at 400, if i hold head, im hitting center mass. Longer engagement range.

Between the two, ask yourself how small a target you are engaging, and how well you can see. Some people literally cant see a man at 400 well enough to engage, so that would be wasted.

this ^^^ my vote 50/200 zero

It has been said, its really match specific, but after talking to a bunch of Iron Sight / 1x 3gun shooters around the country the general conciseness is to use a 300 yard zero, that way you only need to hold under for everything else thats closer (easier to hold under then over with irons). I can't remember off hand but 66yard depending length of barrel and ammo used will put you close to a 300yard zero, this will help you save some time adjusting and you can always fine tune on the 300yard mark. Also when you get your zero, pull it off the table and try to shoot it offhand, prone unsupported, sitting, and knelling you'll find that sometimes you'll "lose" your zero and thast because your head while zeroing is more relaxed and slumped over on your buttstock, when in other positions (specially in competition) we have a tendency to stiffen our heads causing a different sight picture. causing what we believe is loss of zero (nose to charging handle anyone ) It less noticeable with scopes but a PITA with Irons and Reddots.

Heres what one person that shoots irons use to zero at 300yards and explains how he does it.
