What distance should I zero my red dot scope?  100 yards?  

Just want to get some opinions!

Thanks!

so 50 yards is like a general rule of thumb for red dots?

(BTW, I only have a Simmons 42mm red dot as I haven't saved up for a AP just yet)

Mines at 100 but I guess its to each his own.

1 mile.

That's what distance I usually shoot aircraft out of the sky with my terrorist black rifle.

50 Yards

The Maryland AR15 Shooters Site has a technique for an improved battlefield zero.  If  you zero at 50 yards, the bullet is on its way up when it crosses the line of sight.  It then crosses the line of  sight on the way down at  200 meters.  With the improved battlesight  zero you will be +/- 2 inches from zero to 250  meters.

Varies by caliber...

For .223, 100yds for all optics

For calibers with more 'drop', adjust as needed...

Yea, but now that the AWB has sunset, many of us will be zeroing in at shorter distances; you know, to shoot helpless women and children at day car centers, right before sticking them with the bayonet and collpasing the buttstock so we can "easily" conceal it for our get-away ...

You know ... we've ONLY had 12-13 people chime in to say "50".

I don't think that's ENOUGH.  We need MORE people to say "50" before it's truly believable, right?

I know I am in the minority here and I might get seriously flamed for saying this, but I've had good luck zeroing mine at 50 yards.  Unconventional and not too popular around here, I know...

If you zero at 100 the bullet will always be low except at 100.  Good zero if you always want to hit low or aim high.

An inch and a half low at 100 yards?

If you zeroed at 100 you can't be 1-1/2" low at 100 by definition....  

If you zero at 50 yards you'll be within 2" of line of sight at all ranges from spitting distance (this is a technical measurement) to 220 meters.  

Same sight picture for all engagements:  Center of mass.  If you miss you didn't do your part.  Do not aim high unless you're shooting beyond 220 meters.  Even 300 meter targets will fall with center of mass shots.

This is battlesight, not benchrest.

Would'nt the same be true (within 2" from spitting distance to 220 meters) even with a 100 yard zero, only that you would be 2" high at 100yards instead of 2" low at 100yards?

2" is 2" be it high or low, correct?

Not really.  If you zero at 100y that is your zenith, from then on your round will be dropping.  It reduces your range.  With a 100y zero you're already 2" low at 200y and 10" low at 300y.

With the 50y zero you're 2" low at 245y and 7" low at 300

(both calculations assume a 16" barrel, M193 and standard conditions at Sea level).

It's also alot harder to get your rounds 'on paper' at 100y than it is at 50y when you're starting the zeroing process.

50 yd zero puts bullet almost 2.5" high at 150.  Assumes line of sight 2.8" above bore, 3150 fps starting velocity, 55 grain ball (BC .243 according to Hornady).  Bullet is right around 2" high at 100, but it keeps climbing out to 150 before it begins dropping.
