Scope woes, an update!

It is very hard to help on the computer! Was your scope new? Is it possible someone loosened the turret and re-adjusted the stop? The host is a .17HMR?
 
I think I moved elevation turret down 150to 175 clicks. This is why I started shooting at 10yds; then 50 ( which I took a lot of heat for,on this site). I,m new to long range shooting, so I appreciate help. Scope is Sightron Stac,3x16x42.
Is your scope MOA or MIL? Either way, I think 150-175 clicks would still be well short of what you need to move 15" at 10 yards since each click is usually only a fraction of an MOA or MIL.

If you plan to dial for long range shooting, a lot of people zero at 100 yards.
 
I call BS.

15" high @ 10 yards translates into 166" @ 100 yards. Or 158.5 MOA. Or 634 clicks. Each click moves impact .025" @ 10 yards. I don't know HOW you could even get that far off. Considering the STAC has 70 MOA of total elevation travel, it is IMPOSSIBLE you corrected that 15" high at 10 yards.

At 10 yards, your impact should be LOW of POA through the scope. Not 15" high. Zeroed at 10 yards is about a 750-800 yard zero range.
15" high at 10 yards is something like a 2400 yard zero. 100 yard impact would be 166" high. Top of arc would be around 1450 yards, and around 1650" high before starting to come back down.

I think this is either a troll thread, or you have zero clue what you are talking about.

He said he was a beginner, what if he had 20 moa rail and 20 moa rings or any combination of them? Maybe UPS delivered the scope, it could be off 500 moa! And if he is a troll, he would be one of many! Many!!! He could be a young fella, that has no dad to help him. Just say'n!

Nope.

That scope only has a total of 70 MOA of elevation adjustment. No way does it have enough to correct from being 15" high at 10 yards.

40MOA combined is not enough. Lots of guys running 40MOA rails for ELR. But you would need 166+ MOA to get 15" high at 10 yards. You would be looking through your barrel in the scope view.

He also ststed he is more knowledgeable than any gunsmith in the area.

As I recall,I got POI about 4" high @10 yds. Then went to 50yds. To finish zero.
 
Your scope apparently has an extraordinary amount of adjustment because it would take about 150 MOA down elevation to move, at 10 yards, from 15" high to POA. Then, with something like a 30-06 and 180 gr bullets, you would still have to go down another 10 MOA or so from that 10 yard zero to zero at 50 yards.

BTW - with that scope, and with the results you are reporting, you would be better off with a 0 MOA rail than the 20 MOA rail you have.
The S Tac 3-16X42 has a maximum internal elevation of 70 MOA up and down adjustment. This means he can get ~55 MOA (70 MOA/2 = 35 MOA + 20 MOA) total up adjustment when zeroed with 20 MOA. A 20 MOA should be fine. I have done this with a few of my LR rifles. Even though the scope has enough internal adjustment for 1K, it is best with a 20 MOA cant.
