scope help

I got a leupold 6-18x40 with the turrets yesterday and put it on my weatherby today and went out to sight it in....i bore sighted it fine then moved out to 100 yds and could not get it to group at all...i think 5" was the best group  i could get and still had a few strays even with that group. before i sent the scope to leupold to get checked out i figured i would ask you guys for your opinion...i added a picture and theres 6 shots and you can see they were jumping around all over..ive had this only happen once to me and the crosshairs were loose and leupold had to fix them.

Loose bases ?    If you have weaver bases chuck them and go to leupold bases or better. I have had a vx2 on my 30/378 for years and it's never lost its zero.

Yeah, it's moving. Inch pound torque wrench!

[coachcw]

Not a bad idea to have a wheeler around

[deerhunter_98520]

theres solid...atleast i cant feel it move at all....there the same rings and bases i had on my previous vx2 3-9x40 and had no issue with it

[coachcw]

Try a different scope and see

i just took the 3-9  off today and it worked fine before...should i put that one back on and see if it still works? fine?

Is that a new or used/second hand scope?

[coachcw]

That's better than sending in a good scope to get fixed

[2labs]

I'm not an expert by any means. But I never like my bases up against. The bell.

[deerhunter_98520]

true.....it was a second hand scope...got it from my buddy...he had it on a  7mm mag

[Blacktail Sniper]

Probably worth it then to swap back to the scope you know was working and send a few down range to see if it is back on track.

That should be the fastest way to eliminate any mounting issues, if everything is tight and straight and it shoots true, you know the "new" scope is the problem, then you can box it up and send it in, and put this problem to bed.

Like coaches idea, put a different scope on that gun to check or put that scope on a different gun for testing.  But probably loose tube---maybe stripped a little if someone tried to adjust too far?

[deerhunter_98520]

everything looks good that i can tell but who knows...ill try the other scope and see how that does and if it shoots good groups then ill send the scope in
