Anyone else have this problem?

[crnbndr]

I put a leupold 6x18 vxll on my rem 700 sps in 308. I sight in for 100 yards.  Set the zero. Crank it up to 400 yards and the horizontal is off by as much as 6 inches. If I go back and forth from 100 to 400 it seems like it takes 2 - 4 shots for the horizontal to settle in. What's up?

Scope needs to be looked over by Leupold and serviced. I have yet to have that problem with a Leupold but I have had that issue with 3 Vortex scopes. Two of which I sent back and the tracking was still a issue after their return. I could shoot a 1/2" group at 100 yards, dial my 600 yard and the first 1-2 shots would be up to 8 inches out before it pulled to zero. Then I would dial back to my 100yard zero and it would throw the first 1 or 2'out then settle down and track. Absolutely worthless when it comes to long range Rockchuck or Coyote hunting. I ditched the Vortex's and went back to Leupold.

Are you sure it's 100% level?  Like "+" and not "x"

This can also happen  when you are near end of travel in either L&R or U&D. And why I have xtra x-hairs for elevation, once sighted in I can hold over EZ.

Have seen this quite a few time with Leupold and other scopes. Improper mounting was usually the culprit. If you mount the scope off the center of its adjustment range, then install into rings UN true, putting a torqueing twist, you can bind the erector tube against the spring, damaging it, and causing it to float between shots. Send back to Leupold..

Mounted on leupold one piece base and leupold rings which I lapped prior to mounting. Doesn't seem to be at the ends of adjustment.

Sounds like you did it right, obviously not a operator error. I have a 6-18 VX-II I have had for many, many years. I have used it on many rifles and shot allot of big game animals and varmints with it. It's almost like a lucky "Rabbits foot" scope. The scope has tracked excellent as well as any other scopes I own or have owned, just not as clear as NightForce and S III's.

Leupold's customer service has been great for me, usually back in 7-10 days. Only time it took a little longer was when they were working on a large order of MARK 4's being routinely serviced for the Marine Corp.

Are the barrel/mag well/stock screws tight ?

[mountainman]

Sound like you have a lemon Leupold. Send it back and let them repair it. Sad to say, they are not built like they used to be

[Biggerhammer]

Maybe it was shipped with some Kotex's, I mean Vortex's and caught a virus.

I know that this issue has been experianced with Vortex HS scopes but havent heard anything bad about the Viper PST's. I own two Viper PST scopes and am extremely happy with them. Just defending my brand

as a retailer of many brands of optics for the past ten years, I have sent far more newer model leupolds then all others combined. The do have a good warranty, as most optic manufacturers do. Send it back and they will fix it for you..

[Heredoggydoggy]

One of the reasons I retired was the change in the workmanship mantra:  Instead of taking the time to do it right the first time, it was "Throw it together and we'll fix it later".  The volume of product they need to pump out to fill the demand these days doesn't help matters either...

What he means is that if the scope is not level when it's mounted, it will be right on at the distance it is sighted for, but will be off windage-wise when it is readjusted for another distance.  That's why bench rest shooters sometimes have a bubble level mounted right on the scope, so the shot isn't off because the gun/scope assembly is "canted" when it's fired for score.  But from your description of the problem, I don't think that is the case...

I think what they call it is stiction which is the scopes willingness to move after being adjusted until it is hit with a large amount of vibration research this i think this what you might be looking at

Leupold will take care of it if it is a scope issue. I once purchased a used Leupold that look as if it had been used as a boat paddle. I called them and explained that if was purchased used and abused. When I asked if they would honor the warranty, the guy replied, "We made it didn't we?" Three weeks later it was returned and worked like new.
