View Full Version : Having a bit of trouble zeroing my mossberg ATR-100

I cant seem to zero at 150m for some reason. Tried a few kinds of ammo but she tends to like the federal ammo more. Any pointers?

Are you getting any kind of group at all ? Have you zeroed at any other distance ?

Mine is perfect...the farthest I've shot was 300 yards...but from 80-150 I've been within 2 inch group. It was bore sighted when I purchased it. Mine is chambered in .270.

First we need to know what you did to get to this point. Did you start at 25-30m to make sure it was on paper? Shoot 2 shots there, move it so that your point of aim is about an inch higher than the point of impact.

Now move to 100yards/meters and get a group. Adjust your cross hairs accordingly. At this point, you should be in business for moving out to wherever you want. 2" high at 100 yards pretty roughly equates to being zeroed at 200 yards assuming you are shooting like a .270, .308 or .30-06 type rifle. What caliber are you shooting? Scope, open sights?

What kind of groups were you getting? What are your expectations? Do you know the fundamentals of shooting?

Agreed, we need more info.

But also if you have a cheap scope or mounts, that could be the issue
