Whats your Red Dot Zero? 25-50-100 yrds?

[spamsammich]

correction sorry about that, meant yards.

not a problem really. The really confusing point is that with the 50yd zero, your next zero point is at roughly 200 METERS. I'll bet there are a few people out there that have fits checking zero at 50 yards and 200 yards, wondering why their POI further out is so different than what is typically reported with the Santose 50yd BZO.

The confusion is being caused by ammo selection and the fact that these charts are in yards, not meters. These graphs appear to be for M193. A 25m zero with M855 generally results (depending on a number of factors) in a zero at approx 300m.

Ammo and meters:yards (1.00:1.09) variance were the only things I could think of when I pondered those charts but some of those 30 yard plots looked far more extreme than I would have expected. Can I assume that ammo selection is the predominant factor that will skew the presumed 25/300 meter (?yard?) return to zero point, and that I just learned that knowing one's ammo is critical in anticipating predictable shot behavior at significant distances from zero?

Found this article on the CSAT website directly pertaining to this topic, so I thought I would post it up for all to take a look at.

The Battlefield Zero

He starts off by making the point someone else made at the very start of this thread

Nothing confirms a zero like walking the actual ground and checking the hits on your target. So put away your graphs, charts, knobs, etc. and let's look at some holds and shots.

No, it doesn't. An M16 zeroed for 25 meters using M855 will have a far zero well beyond 300 meters.






Also, the trajectories for M193 and M855 out to 400 meters are nearly identical.

Not with an M4.

Aimpoint M3, 2 MOA zeroed at 100 yards on HK 416D. Shooting the offset at closer distances.

Could someone show me how to generate these charts?

I am looking to characterize a 10.3" SBR firing XM193, M855, and MK262 with a 25, 50, and 100 yard zero.

May reconsider my 50yd zero, 100yd zero is begining to look better.

Coming from a Army shooting background.. this thread is incredibly helpful. I have just been converted to the 50 meter zero.... if the data truly adds up.


Anyone know where I can buy some 50 meter zero targets? I have a ton of army issue 25 meter zero targets.

The targets are irrelevant, as you are always shooting center of mass. As long as they are large enough for you to see. I've used the standard 25 yard pistol targets, 6' Shoot and See, as well as the 3' ones at 50 yards. The rest, is up to your own individual shooting ability.

Hey HOLD ON your telling me you have to zero these things WOW no wonder i cant hit anything Just kidding i use the 25m zero or bore sight laser with target
