Steyr LG110 ft scope rings query

I am looking for some information.
I have Steyr LG110 FT (16J) with the standard Steyr Weaver rail. The scope is Sightron SIII 10x50-60. With current rings the scope center line is 58mm above the bore center line. I measured this via the foil and pinhole method. The rifle shoots really high @25M. I had to turn elevation knob 1.5 turns from optical center to bring the POI down.

Looking to see if someone else has been in the same boat and how did you solve this problem.

I am considering to purchase a set of adjustable rings to solve this issue - Burris XTR or Sportsmatch ATP 72. If someone uses Burris XTR what model do you use and how do you like these in terms of adjustability and in general.

thanks

You will be "clicking" around optical center. Don

Have not decided if i am. The scope is MOA-H so I can hold over. I am considering this as a strong possibility.
Come to think of it, i do not understand the reason for "about perfect", can you please help me understand.

The higher the scope is the farther out your zero point will be. And, more holdover or clicks will be required for close targets.

Tony the scope rail probably has some elevation compensation in it and if it is shooting 15 minutes high at 25 and the windage is about centered, I would say that is good. If you are going to click you will be clicking up nearly a full revolution at 10 yds and if you are going to hold over it doesn't matter.

Terry, i just shot 10m with optically centered scope. It shoots 5MM high and 5MM to the left. Not too bad for 10M. But playing with the chairgun i see that the trajectory hits 5.3mm high at 10M, then up up and away, close to 30min at the apex @50M. I have measured the velocity, and it is @795fps average of 10 shots. I know I can't completely trust the cheairgun, still it is a reasonable approximation.

Tony if you want to get closer to optical center, get the Burris "Z" rings, medium ht. https://www.midwayusa.com/product/15483 ... ings-matte
That will come with a 2 sets of +/- .010" inserts that should be about what is needed depending on your ring spacing. If your rings are spaced 4" apart you will get roughly 20 MOA of adjustment. Or just use 1 set of .010" inserts and get 10 MOA. They can also be used to offset windage .

Tony sportsmatch all the way I just set up a styer challenger with a Sightron slll had the same problem. The sportsmatch rings are adjustable by a small Allen very handy. This is what I did (you will need two people , one to shoot and hold the rifle and one to adjust the rings.
1. Optically center your scope.
2. Set out target at a distance you want to center your scope at .
2. Shoot the rifle from a rest or bags at a dot on the target , aming point and pellet hole have to be visible.
3. After the shot, sight on the aming point again. once you are sighted on the aming point do not move gun! Hold the gun on the aming point while looking through the scope,
4. have your steady hand helper loosen elevation locking screw on both sets of rings just enough that they can adjust elevation on the rings using the supplied Allen key .
5. While holding the gun still, looking through the scope and cross hairs on the aming point have your helper adjust the elivation of the rings while you call out directions (did I mention do not move gun) until the crosshairs hairs are on the pellet hole.
6. Lock down rings and fire another pellet at aiming point if you hit your aiming point you are centered. Repeat if nesscary.
I am no expert but this worked for me.

Thank you. I understand what you have done. few follow up questions.
- based on the description, i think you used ATP72. Did you need to adjust the windage using scope then? what is the reason you decided against ATP66 + RB6
- what did you do to line up the center line of the bore with the center line of the scope to ensure that the pellet travels in line with the vertical reticle. Assuming no wind and the scope is perfectly plumbed

thanks!
