Zeroing an AimPoint Red-Dot? Issues...?

So if you were getting 2 inch groups at 25 yards, you would expect 4 inch groups at 50 yards, although the center of the group would be less than an inch higher than before. It still should be on paper.

Remington supplies a ballistic chart (that I've linked below) to show you how their bullets arc. For example, if you zeroed in at 50 yards your round might be half an inch higher at 100 yards, and then back to zero at 150 yards, dropping off at 1.7 to 2.3 inches below zero at 200 yards. Sadly they don't supply information at 25 yards because that's a little short to be shooting rifle rounds.

Since it's pretty hard to miss a paper target entirely at 50 yards, I don't think it's your marksmanship at issue (like I explained above I'd expect a 4 inch group at 50 yards). My first guess would be that somehow the sight might have been jostled or gone loose (I'd also guess a sight malfunction if it weren't a high quality Aimpoint). My second guess might have to do with the rifle, that maybe you somehow were holding the rifle differently to adjust the point of impact. For instance, if you zeroed you rifle while using a bipod and then removed the bipod that might cause a problem depending on your rifle. My last guess is the ammunition, which just might have been a bad box. It happens, and Remington ammunition isn't too high up there.

A 2 inch group at 25 yards is pretty okay. This translates to an 8 inch group at 100 yards (roughly 8 MOA), which isn't bad at all for a beginner who's not using magnifying optics. But are you getting the maximum accuracy out of your rifle? Probably not, but for most of us our rifles are better shots than we are anyhow.

It should have only been 1.3 inches high at 50 yds if zeroed at 25 yds. I am not sure what is going on there. For a rifle with decent range, I typically bore sight, and then sight in at 50 yds. Then move to 100 yds, and then to typically 200 yds. I normally zero at 200 yds for rifles with a muzzle velocity of over about 2600 fps. A 2" group at 25 yds is an 8" group at 100 yds. My son has an upper that we built and shooting hand loads, it gets touching bullet holes at 100 yds. That is about a 0.25" group. All of your bullets should have hit the part of the target that had "10" printed on it. There should have been bullseye all around the hole from the bullets.

Where you shooting off a bench rest or standing and shooting offhand? 2" is OK fine for 25 yards if it is offhand. Since your sight is higher than your bore and the bullet's path makes an arc in the air, you only be zeroed exactly at two points in the bullets path, the upward part of the arc and the downward. You should be high by 1-2" at 50 yards since a .223 bullet will still be raising at that point, so you should still be on paper.

First you shouldn't be zeroing a .223 at 25 yards. And yes 2 inches at 25 yards isn't good. If I couldn't get minute of angle (1 inch at 100 yards) I's assume there is something wrong with the gun or the sight.

I'm willing to bet though i is the shooters.

nicely maximum weapons use a front and rear sight you will nonetheless be precise you may merely could desire to comply with it. additionally i think of the iron attractions on a AK47 suck so something could be an progression.

dont know but 2" at 25 yd is TERRIBLE. what kind of ammo was he using?
