I would be suspicious of the optic bases or rings not being parallel with the bore of the barrel.Originally Posted by M-Tecs
There are many different possible reasons for that but as others have mentioned, that's just a guess due to the limited information.
The rifle already came with a 20-moa rail, so
I used a 0-moa Sphur mount, which I took from my 6.5 CR with a Leupold Mark 4 scope, which I used for long-range shooting with success up to 900 meters.
Everything was tightened with a torque wrench, 20 lbs/inch.
Four people looked through the barrel and through the scope at a target at 100 meters.
We shot Federal Gold Medals.
More info??????
Yes. How did it group and was there enough adjustment to get it on paper?

When all else fails bring the target in closer till you get impacts and adjust from there.
Agreed. No matter where the point of impact is, shoot it 5x. If you have a small group then the problem is the aiming system, not the rifle. If you have a 3 meter spread...... well. I've never seen that. Is the ammunition correct for the chambering? A 6mm bullet won't shoot accurately in a 7mm bore.
The OP is in Buenos Aires, Argentina so ammo might be limited or very expensive? In the states most of us would shoot it until we had an understanding of the what's and why's before contacting the importer or manufacturer. At a minimum I would want to provide them with how far its off POI when the scope was optically zeroed and group size or if the bullet holes were not round or showed signs of tumbling.
Mistakes do happen. A friend ordered a higher end semi-custom rifle in 270 Win. It was stamped correctly yet per bore size it was 7mm. .277" bullets in a .284" bore don't work well. His last name is Cooper. Three guesses what brand rifle it was? They made it right and gave him a free upgrade on wood on the replacement plus some ammo. The first stock had very nice wood. The second stock was breathtaking.

If you can't afford to shoot a rifle 5x to verify the POI matches the POA or bought ammunition based on price or availability instead of verifying it matches the chambering .........
In the US it is hard to comprehend two scopes tried with a total of 20 rounds fired. If ammo is limited by Argentina's laws is become much more understandable. I am an avid prairie dog shooter. I've had several days that were 1,000 round plus days. Most of the rest of the wold can't comprehend being allowed to have that much ammo let alone shoot it is a single day.

Well again, given information at this point, I'd verify the chambering matches the ammunition being used.
Read the first post again to be sure. Not on the paper at 50 meters. After 2 tries the next should have been at 25 meters or less. Once on the paper there will be indication of whether the problem is the gun itself or the sighting system. Then there will be a chance for resolution.
Spell check doesn't work in Chrome, so if something is spelled wrong, it's just a typo that I missed.
this!!
yeah bore sight it at 100yards - but the first shots should be up close - cant hit paper close in ? anything else will be a waste of time and energy until you can
that said - I have a post '64 winchester model 70 - if you pull the middle action screw down tight on that rifle ruins its accuracy (glass bedding would proly change that but dont overtighten that screw and it still shoots MOA.) sometimes dumb little things bring us undone

This is what I do. My first shots are at 25 yards. Then you have a base line to work from.
The OP is not an amateur. My bet is there is something wrong with the rifle or mounts as he used a proven scope.
I don't agree with the cost of ammunition as a good reason to limit the number of shots needed to evaluate the problem. There is no other way to understand the problem without rounds on paper.

if the point of impact is far above the point of aim through the scope, then the scope is not set correctly.
You could not have boresighted this by looking through the barrel, and dialing the scope to the same point, or else it would be on paper.
At 50 meters, even if you shoot through a unrifled tube, it's going to hit paper.
The problem is between the trigger and the bench.
Send it back.
Whatever!
I've been thinking a lot about the issue.
The ammo is correct. All the mechanical parts fit with my new torque wrench.
Four of us checked the adjustment between the scope and barrel. As mentioned above, I'm not an amateur. I'm a surgeon, so you can bet I'm very meticulous about things.
I think I may have made a mistake. Everyone present saw the dive above the target.
What happens if the bullet passes below and what we see above is thrown dirt?
I only focused on shooting low; I never tried to shoot higher.
On Saturday, I'll go with a larger target, some more bullets, and a new spotter.
I fixed that to ensure you can move forward. Zero reason to be throwing lead at 50 yds and guessing where it is going. Move the target to 15yds and set the scope for a POI 6" high. That should get you close at 50 and 100yds.

The problem is that I'm not on a private range; the range is pretty strict about distances, and the shortest is 50 meters.
I have to request special permission to shoot closer. I figure, knowing the problem, they'll give it to me...
Will they allow a larger target like a refrigerator box?

that is easier to achieve
When I was patterning shotguns I used rolls of paper. Easy and not expensive. IIRC, they were about a meter in width. Take some PVC pipe, or if windy 2x4 lumber, to the range and make a tall target. You will hit it at 50 meters.
