Having trouble sighting in my XCR, have a bushnell ar scope 3-9x40 with a Nikon m-223 mount. Was at the range last night to sight in my scope and the point of aim seemed to be moving and scope didn't seem to be tracking right. I was shooting low at 100yards moved 8 clicks up and poi moved over about 6" right. There was no consistency in where the poi was. Shooting from a sand bag, scopes tight and barrel screw is torqued proper. Does it sound like the scope is bad?
 
start your sighting in at 25 yards. once your good there move to 100 to refine it.
saves ammo. otherwise if using fmj or inexpensive ammo, you could chase it all day
my 2 cents
 
8 clicks should have moved it up 2 inchs , if it’s 1/4 inch values.

It’s maybe your dials are messed up.

Or your barrel is misaligned.

Try a different scope.
 
A couple of things. First off, you didn't happen to mount the scope a quarter turn off so the elevation is now the windage? Don't laugh, I've seen it before. The most memorable time was a guy who couldn't sight his gun in and asked for help wanted to argue when I pointed out his scope wasn't mounted in the conventional fashion. He pointed at the dial where it said "up" as proof that he was turning the right one; even though it was now on the side. He did eventually catch on to what I was telling him, and I didn't even have to resort to my lucky 2 x 4. It was close though.

Mounting can be so far out of whack that windage is affected by elevation. Picture a tube inside a tube. If the inside tube (erector assembly) is crammed against the side of the scope body cranking it up needs to move it sideways.


Or maybe your scope is pooched.
 
Since it's an xcr, what you need to do first is make sure the barrel retention screw is really torqued in otherwise it'll do what you are describing. Check that before messing around with the scope.
 
I can't think of any situation where 8 clicks would give you 6" of movement at 100yds. 1/4moa clicks would only get 2", and even 1/2moa would only be 4" shift. Plus, you know, the whole moving to the side not up...

I'm going to assume you haven't done what dogleg suggests (mounting it 90 deg off) so I'd lean towards a scope issue.

Was it grouping at all? Did you shoot a few shots before messing with the scope? Did they group together or go all over the place?
