    The graphics below illustrate and compare different common zeros and the impacts they yield at various ranges. The graphics show points of impact for a given zero using various common barrel length and popular ammunition combinations. The trajectories of M193, M855, and Mk262 ammunition is illustrated with velocities adjusted for the given barrel length in an attempt to give most shooters an idea of what their set-up is doing down range. These are meant to be a quick visual reference. There are far too many factors that come into play for these to be 100% accurate for every set up and situation, but they will get you close.

    The graphics use a standard IPSC target for scale. The red dot is the point of aim with the black dots being the point of impact for the given distance.

    Hopefully you guys find these to be helpful as an easy way to see what your chosen zero yields with your set-up.

    I’m still working up graphics for 11.5”, 12.5”, and 20” guns and should have them up soon.

    Great on ya for putting this info in a format more shooters can understand. If only now we could get more shooters to learn to ZERO their rifles ...... In under 10 rounds!

    That is a very helpful illustration. I can tell you that the 55 grain 193 out of a 16" barrel matches the graphics well. My optic is zeroed at 50 yards

    Excellent! Thanks for sharing. Can I ask what type of optic and mount you used? Just so we can get an idea how our scope height and barrell bore distance compares.

    Edited to add;

    Only interested in the 16" carbine.

    These are created with a 2.75" optic height. This is somewhat of an average height, so the graphics should work for those using a lower 1/3 co-witness and an absolute co-witness.

    I've still got my range books from while I was in. We would do a 36 yd BZO which would be like shooting at 300yds.
