Dead on at 400, gun shoots left at 100?
I am shooting 1" to the left at 100 yards, but I am dead on at 400 yards....what is my problem? I do have a scope level on my scope, that is leveled with the scope base. Thanks for any help.
gun is savage 338 lapus fcp, nightforce 22x

Spin drift may be the answer. If you have a right twist barrel, as most are, the bullet will drift to the right a bit over it's flight. Some guys deal with it by zeroing a bit to the left at close range, as you are. Might just leave it alone at this point, unless you are planning on taking some much longer shots.

Probably no problem at all. If your rifle has a right hand twist it could easily be moving that far right at 400 yards. My .243 moves .8" at that distance.

Be sure to check/ adjust your parallax.
Be sure to verify your scope is actually level with the action.
I'm sure you know this one, but scope levels can be mounted out of level.

I would think SD would only move you .25-.5moa at that distance. I would double check to make sure your cross hairs are indeed level. Was this a one time thing or have you tested this on different days. If this was a one time thing I would do it again. Wind can play games with you.

if my crosshair is wrong, which way do i turn the scope when looking thru it...also
what is the best way to check the scope level...shoot at yards, then adjust the scope to the 400 yard mark and shoot it again at 100?

Draw a long vertical and horizontal line on a piece of butcher paper with a level "after you have taped it up", shoot a 100 yard group then dial up 30MOA and shoot again. That will tell you if your scope is level or not, keep your reticle perfectly on the horizontal and vertical lines for both groups
