Problem solved: Scope windage maxing out.

Someone talked about using set screws and adjustIng the barrel with those. Pushing it to center I suppose. Look into it

My Bobcat did that so I ordered adjustable rings for windage and elevation . Set your scope windage to center and adjust the mounts until your hitting the target. That way your reticles are in the center of your glass.

I had an Air Arms S510 FAC that did the exact same thing it drove me absolutely crazy. I wanted to sell it but I didn't want to screw over the next buyer. Finally I called Allen Z and he told me how to remove the shroud and re-align the barrel in the action. Because the gun was shrouded I couldn't see the misalignment. Also just a little tiny bit of movement equals a lot of POI change. When I loosened the screws the barrel realigned. You know it's not pellet clipping because the gun holds zero. 

"blackdiesel"I have a gun and have tried two different scopes. I have to max the windage to right to zero it. One scope I am able to zero but one the POI is still wide right. I checked the scope rail and it seems to be straight. On the gun I was able to zero it shoots one hole at 50 yards and I can plink cans at over 100 yards with no problem.

Adjustable wind age rimgs is one option. What scope rings are you using?? Trying swapping the rings you use on the good scope and put it on the one that shoots towards the right and see if that fixes the problem.

I had the same problem but I realised the rings I was using on the scope were a problem. They were cheap ones and didnt align properly. I ordered the BKL self centering rings and the problem got solved. Usually the rings that are available sometimes don't align perfectly thereby causing the pellet to hit towards the right at 50 yards. A good way of checking if your rings are a problem is to see this video. 

Beagle's correct and may be I can elaborate on that.

Find the optical center by spinning the scope in the rings and sighting thru the scope while watching the cross hairs. Adjust the turrets until the scope hairs remain centered as you spin the scope - you should then have the recital in the optical center. Mount the scope on the rifle and see were it groups. If its way off, swap the rings end to end and recheck. Still way off rotate one of the scope rings as often the rings clamp from one side and depending on the width of the rail the rings will be off center. Keep switching them around until you get the closest POI to the line of sight of the scope and if it is not to far adjust with the turret. If it is still too far off you can shim between the rail and ring - at the dovetail to move the center of the ring over. I have used brass material purchased from the hobby shop.

Shooters who participate in Field Target set their scopes up for the POI to be on target at 55 yards with the scope very close to the optical center. Usually there is a need to shim under the rear scope ring to get enough down tilt in the scope to achieve this in the elevation - but if done incorrectly can damage the scope. Or the ring is recut using a mill to relocate the rings center or you can purchase droop barrel scope mounts that compensate for this. Keep in mind that the torque at the rings, where the scope attaches to the ring mount, is not very much - maybe 10 in-lbs or less - it's a lot less than you think - check your instructions. That means if you take a 10 pound weight and attach it on your allen wrench 1 inch out from the center of rotation, that would develop the required torque.

That was probably a bit long winded and more than you wanted to know - good luck.

Edit - you guys are fast on the keys!

Two things I would like to interject:
1st-The easiest way I've found to achieve optical center is to place your scope's objective end tight against a mirror and adjust the turrets so the reflected image of the reticle is transposed perfectly over the actual image of the reticle. (good light and scope off gun) You'll get the idea when you try it and it alleviates the need for having the rings and rifle anchored perfectly while trying to spin.
2nd-It's a crap shoot but you can also try reversing your rings front to rear and also switching one or the other to have set screws on opposing sides. This has worked for me even with high end rings on my high power rifles.
