For optics that REQUIRE 100 METER zero HELP!!

[equilibrium]

Alright man thanks for all of your help. Ill continue my search and see if I can find a comparison of the trajectory patterns for the 100 meter vs 100 yard.

With 193 don't worry about it. You aren't going to kill any deer or hogs at 3-400 yards anyway! 556 was never intended to kill things at that range. Not animals that don't know what hurt is.

Are you looking to see what the difference is at specific ranges (100 yd/m, 200 yd/m, 300 yd/m, etc...)?

Yea i hear ya! Thats why i stated that I wasn't intending to shoot very far. I just wanted to make sure that with 55grain (SP, FMJ, ETC.) that I wasn't going to be too far off on the BDC. I know a lot of people zero their ACOG at 100 yards and it is fine. I am assuming that within 200 yards the difference in trajectory will not even be noticeable unless you are a sub MOa shooter and same probably applies to the further distances. I was just obsessing over it because I get like that sometimes, but feel a lot better now.

I sighted my TA31RCO (chevron) in at 100 yards and have shot coyotes at 300 yards several times using bdc. Great optic for that range. I don't shoot past 300 with that setup and reticle.

Yes that is exactly what my next step was going to be!! That would help me understand my trajectory after I zero at 100 yards.

I do not plan on going past 300 either. The only time I shot past 300 yards in my life was during the range qual. Good to know that you zero'd at 100 yards and were effective out to 300. I kind of figured that the trajectory difference in range/yards couldn't be outside of + or - 5 inches.

Zero at 100 yards will put you -12.98 inches at 300 yards and -17.07 inches at 300m (328 yds).

The POI delta between 100yd and 109yd is going to be less than a click, so I wouldn't be concerned about that.

For ACOGs and similar BDC setups, it is possible to start off with a zero for 300m on the tree at 36yd - it's not great, but it gets you close very quickly.

I get that the range stops at 100 yds., but if there's a chance you could put up a target at about 23 yds., do you think these would help?
