View Full Version : Scope Alignment Question

I just re-mounted my Leupold scope in my 110 and since I have an almost insane desire to have the scope line up perfectly with my eye when I rest my cheek on the cheekrest, I adjusted the rear mount in towards my face so achieve the desired result.

Now my question is, assuming I have enough horizontal crosshair adjustment, will this affect scope performance or cause parallax issues. It might be 1/8" or possibly 3/16 off center. In my mind, once and if it gets zeroed at 200 like I usually do, will horizontal POI change with distance or will it not matter? My assumption is that it won't but I haven't been to the range with it yet, but with the cost and availability of ammo and supplies, I don't want to waste a bunch trying to figure it out.

Disregard, I didn't understand what was being asked when I first read it

If its off it will change how your scope reacts to adjustments.

It won't matter. When you sight the rifle in, you'll be moving the internal optics to place the bullet on the target. The external optics won't change. You may run out of adjustment before you get there though. When using Leupold style adjustable rear bases, I generally center the internal optics and then with the assistance of a boresighter, tighten down the screws as near center as possible. That gives me equal adjustment in both directions. Not that that really means anything. I can't remember the last time I actually moved the horizontal plane once a given rifle was sighted in.

Sounds like a real bad idea to me.

Scopes are happiest the closer they are to being mechanically/optically centered.

I would rather move my face to keep my scope happy than swivel the whole scope towards my face.

I think you will be exceptionally lucky if you have enough windage to compensate for what you have done. It does not take much actual movement to move the POI 1 inch at 100 yards. Seems to me it was something like 0.001 inches at the scope to move the POI one inch at 100 yards.

Now let's take a typical scope that has say 50 MOA of windage adjustment. That's 25 MOA left and 25 MOA right, or 0.025 inches to each side.

If you pivoted the scope 0.1875 inches (3/16 inch) there will be no way to overcome this using the built in windage adjustments.

In other words what you have done is a really bad idea.

unless you move the front and back equally creating an offset scope mount. of which I don't really like either...

You should market that, I think you found your niche!

OK pert near forgot I posted this. Sorry about the absence. OK I will re-center it. I still haven't got to the range yet so I never tested the theory. I knew it would take a lot of horizontal movement to zero, but wasn't sure if it was a totally bad idea. I THINK it might work, but at the cost of ammo, even reloading, it's probably not worth the effort.

And no I do NOT want an offset scope mount either. A centered it will go.

Thanks

It was just a "cock eye'd" idea anyway:(

Hey Handi, You aren't the only one who likes a good consistent cheek weld, usually though, the stock gets adjusted.

Bad idea! Keep lined up with the barrel.
