sight zeroing question

im running dd a1.5s on my carbine. I brought it to the range to zero yesterday but only had time to do a ten yard zero never got to walk it out . But to zero at 10 i had to pretty much bottom out the front sight and have no adjustment left.

Wondering, as a walk out the distance will this be an issue that corrects itself?

Im also wondering, does it have something to do with the sights not being meant to be on a 15 inch rail? Excessive radius?

At ten yards, you should have been aiming at the bullseye and the bullets should have been hitting about 2 1/4” low. A bullet always travels in an arc. You will end up with the front sight being adjusted to very near where it was when you began. What was point of aim vs point of impact with your first shot?

You should be fine. I’d suggest starting again at 10m, get the bullets hitting about 2” low. Then you can either jump to 50 or shoot another grouping at 25m.

Have you decided upon what distant you will zero it at?

Measure the bore-axis difference between the bore and your RDS or iron sights.

At the close range you were shooting, you should be "that distance" below your intended POA. Though not "really" sighted in, but at this point you are close.

I choose the 100yd sighting. For my purposes it offers me good "doping" for the distances I shoot.

Ten yards zero you want your group to be 2 1/4 inches low as stated above. Take a blank piece of printer paper stick a Paster on it. Measure the distance from the group and Sticker depending on which hold you use if 6oclock hold then measure from the bottom of the sticker to center of group. If you use a center hold measure from the center of the sticker to center of the group. By doing this you will hold the Xring at 100 yards might have to give a click of windage to fine tune. Your sights are for adjusting at 100 yards so at 10 yards they adjust 1/10 of what they say they adjust at 100.
