Sight in

[MathewQuigly]

When sighting in my leupold, is that done on the max power?

[metau]

For establishing a zero I use max power, but it does not matter what power it is on. It only makes it easier to see the target and maintain a higher degree of precision.

[MathewQuigly]

I ask because when I first got the scope I noticed a change in the point of impact between the lowest and highest settings. I sent it back to Leupold, they said nothing was wrong. Somewhere I read scopes should be sighted in on the highest power, but I'm confused as to why that would matter

[metau]

Not all are calibrated for use at max power, though most are. When the OP mentions sighting in a rifle, I assume he means establishing/confirming zero. Verifying BDC substentions is a vastly different exercise altogether.

 

If you are experiencing a POI shift throughout the magnification range of the scope, then I would demand a replacement.

Thanks for the reply and, yes I was referring to establishing a zero. I think I'll make another trip to the range then call

[metau]

Confirm the zero at several magnification levels. I'd shoot a group each at 3, 5, 7 and 9x on a 3-9 scope, and assuming you do your part, if there is a noticeable issue with tracking then I would send a pic of the target along with your email to customer service showing them that there is indeed an issue and requesting your scope to be replaced.

Ok it's a 6.5-24 x50, love the scope, we'll see what happens

Could be a parallax issue. If parallax is not removed via the side focus knob the difference in your cheek weld from 6.5X to 20X may have an effect on POI.

[MathewQuigly]

Could be ill check that thanks

This is the biggest and nicest scope I've had hope that's all it is

Your zero, wheter it be at 100, 200, or 300, should remain constant at all magnification ranges in a SFP scope. 6.5x, 12x, 18x or 20x.

Parallax, if not properly set (which does not necessarily mean a clear sight picture) will wreak havok on accuracy. To check to see if parallax is removed, make sure your rifle is on a solid rest, and move your head slightly up and down or side to side and see if the reticle moves on target. Adjust parallax knob (or "side focus" until the reticle stays perfectly still on target. If not, what you think you are aiming at, might not be what you are actually aiming at. Parallax gets more pronounced and noticeable on higher magnification. Even a little bit. This is more than likely your problem as C.Cordova suggested.

I sure hope so

Great info! I'm about to sight in a 6-24 power scope.

One of the things I used to struggle with was making sure the reticle was aligned vertically correct. I found that if I leveled the rifle and then the scope to level my natural point of aim was to cant the rifle so now I hang a string 25 yards or more down range in a building and check my verticle reticle to this string when i,m hold the rifle for me. Then I put a bubble level on the scope tube to my verticle so that I can hold the rifle correctly each and every time. It is another way to verify I,m doing my job when shooting.

Ya good info in this thread
