    I primarily use a 100 meter zero, as it gives me standardization with my optics.
    With a new optic I will fire a couple of shots at 10 yards or so, checking for gross deviation and mount tightness. I have had mounts come loose, so I like to make sure that they are good to go before I get deep into the zeroing process only to find out that the mount is loose and have to start all over. After checking everything over I fire a single shot and make sure that the shot is about 2 to 2.5 inches low and centered. Then I move back to 25, fire a few rounds, check the mount, and adjust to about 1.5" low, followed by a couple of shots to make sure the adjustment was close. I try to get through the 10 and 25 fairly rapidly.

    I then move back to 100 meters (about 110 yards). For zeroing I do not bother with ranges that won't let me get back to at least 100 yards. I spend a bit of time at the 100 with 5-shot groups. When I think I am happy I fire a 10-shot confirmation string at a pace that allows a breath between shots and good trigger control, but no slower than that.

    The 50/200 is a good zero as well, and I have really only gone away from it to get commonality between my dot optics, ACOGs, and precision optics. I consider the zero to be a 200 yard/meter zero, with 50 yards as an expedient method of achieving a rough zero. I always confirm at 200. There can be enough error at 50 yards (which may seem to be acceptable) to be distinctly off at 200. With dot optics I use a big paper plate for a target at 200. I consider the final confirmation at distance to be non-negotionable. You simply do not know for certain where you will hit at range until you actually shoot it. Ballistic calculators are great for getting a general idea, and expedient methods at 25 and 50 will get you close, but nothing compares to actually doing it.

    I like your idea of using a black bull slightly bigger than the size of your dot on the target.

    Following that logic with a 4 MOA dot, does this seem right?...
    025 yards: 01 inch dot: 02 inch bull
    050 yards: 02 inch dot: 03 inch bull
    100 yards: 04 inch dot: 06 inch bull
    200 yards: 08 inch dot: 12 inch bull
    300 yards: 12 inch dot: 18 inch bull
    You can go that way, but really what you do at 25 and 50 isn't all that important, as long as you can do it right at actual zero distance (100, 200, or if you are old-school- 300). There are some great targets to get a rough 100 or 50/200 zero at 25 (HERE is one). Obsessing over the close-range expedient methods and trying to make the POI perfect at any distance other then the actual desired zero range is counter-productive and a waste of time and ammo in my opinion.

    An 8.5 by 11 inch sheet of printer paper with a 2" circle or square works just fine....and for $5 you can get several hundred targets.

    What is the size and color of the dot you put on the white paper plate?
    First post here so I hope I do everything right. Any how, I just thought I'd comment on this concept. I tried it, and I found out very quickly its good for getting close, but to zero each sighting system independently in order to get accurate results. If your saying to use this method to get close, I'm sorry if my reading comprehension sucks. I'm just a redneck who *thinks* he knows something about guns.

    I took the targets you recommended with me to the range. Although pretty good, I didn't like them as much as a solid black bull. The white cross washes out the dot a bit imo.

    Seriously, the simpler the better! The only thing I would add to this is that you need to vary the size of your circle depending on the size of your dot and the distance to the target. Just seeing a little border of black around your dot helps to get a consistent POA.

    +1 on the accuracy of this chart. I shot on the 50 yard zero distances tonight, and I am right there on every one. Pretty cool.

    A couple comments:
    Does anyone have the 25 yard zero data, I may consider that over the 50?
    Who the hell would zero their carbine at 7 yards? Talk about worthless trajectory.

    That chart was linked from this article as an example to show how useless zeroing at across the room distances for entry teams is: http://www.lawofficer.com/news-and-a..._gun_zero.html

    The 25yd zero is nearly as useless as the 7yd zero in my opinion.

    Here's another thread which should be helpful: http://m4carbine.net/showthread.php?t=34671

    This printable one has two targets on one sheet. It has a 2" black center dot with an outer 4" ring. At 50 yards the red dot is roughly the size of the center of the target.
