Definitive explanation to Lucy

[Keyman62421]

First, thanks to all the suggestions and explanations. 

My problem was this was a MOA shooter up to about a week ago. 

I indexed and rotated my liner ending up where I started. 

Removed the barrel and aligned the orifice with the block. 

I could zero the gun and take a shot or 2 and be good then all of a sudden 1/2 to 3/4 hash marks to the left. 

I don't know., I am puzzled and perplexed.

Finally, I removed the cheek rest and place a level across. locked the gun in place. 

then I placed a level on top of turret. guess what. not the same. WHAAA? I couldn't believe it.

I leveled scope to rifle. back to MOA @ 100 with 25 and 34. .

I looked through scope and reticles many100's times, and I guess I had become accustomed to the errant alignment.

Any way, it was CANT . Not rifle but scope. Something I should have spotted right away. Why all of a sudden?

We all do it! DO NOT PICK UP YOUR RIFLE BY THE SCOPE!!!!! 

As simple as it is I hope this helps the next shooter.

Dang it Lucy, why didn't you see this????

What makes you think it was caused by picking up your rifle at the scope? Does that mean your rings or mount weren’t tight enough?

this is a question to better understand, please don’t take it as an attack of any kind. It’s just curiosity.

Another forum member @davecole shared a link a while back for a Vertical Reticle Instrument and this is a very good way to make sure your reticle is in alignment.

Good info, thanks.

That scope tool is great in theory, but can fall short on actual delivery. I threw away a GP win by missing half of my 10 and 11y shots after setting up with that tool. Putting levels in your gun and turrets isn’t going to do it, either.

I would recommend not spending any money on that pile o dung.

Zero your rifle at your apex on a vertical line …Then shoot 10y and see if you are off left or right. If shooting right, rotate the scope in the rings a little counterclockwise. Shooting left…rotate clockwise. Recheck your zero…then recheck 10y. Repeat until both distances are on the vertical line.

I cant say that the scope handle syndrome was THE problem. I bump the gun around a little hunting and transporting. Just saying go easy on the scope.

Scope mount screw question. I don't have a torque wrench for these small screws, and I try not to over tighten. I subscribe to the flex theory . Let it move before it breaks.

I was remarking to my carelessness and inattentivity.
