Leupold Zero Point Boresighter

I just received my Zero Point and have a question about using it to confirm zero without firing...

When I move the Zero Point vertically on the muzzle of my 700 PSS with a 10x42 mounted on a 20MOA base, I noticed that the grid is moved as well. Is this because of the canted base? If that is the case, then it is necessary for me to make sure the Zero Point is installed on the muzzle at the exact same vertical position each time in order for the grid to be in the same position, correct?

Also can someone explain what exactly does "The inch scale marked on the housing can be used to set the scope height" mean? How exactly do you use this scale on the Zero Point?

Trust the FORCE. It is strong. After you mark your card you can change to another scope set it to your card, and it will be right on.  Trust

We can also go down to the local gun shop with an ace bandage on your wrist, and tell him your wrist hurts and you can't turn a screwdriver and would he bore sight this rifle please?  HA!                        

This gadget is actually pretty cool.  Think of it as looking into the mirror.  Everything is backward.  The height of the boresighter doesn't have to be exact.  Just measure from your barrel to the topic of the front part of the scope and divide by 2.  Use the ruler on the side of the boresighter to get the height about right.  Adjust the power x to get a good view of the lighted up board on the boresighter.   I boresighted to the hole in the light.  Shoot at target and you should get a shot on the target/paper.  Follow common sense safety and then put the boresighter back on, adjust the boresighter so the grids are square with the scope reticle crosshairs and look through your scope, the optical illusion of seeing through the boresighter, and adjust your crosshair to cover your bullet hole on the paper target.  Remember everything is backwards so you are actually adjusting to hit in the opposite direction.  Once you set the crosshairs on the bullet hole on the target make a note of your setting on the boresighter interface on one of the setting cards.  Now, take the boresighter off the muzzle and your next shot should be close to center of target.  If you do everything right and leave the science stuff out of your head the least amount of ammo you can use is two shot to zero under the right conditions.    You can use this boresight to measure your zero at any distance for quick on zero reference on your rifle.  So, the Leupold Zero Point is actually more than just a boresighter.  It is also a tool for standardizing your zero settings for variable ranges without firing a shot. 

At first I was puzzled but the boresighter doesn't have to be exact at the end of your muzzle. The optics of your scope does that for you.  This gadget costs about as much as two or three boxes of good ammo.  It will pay for itself in time with ammo saved on zeroing the rifle for different situations.

Question on the Leupold Boresighter if anyone can help -- Mine has always worked great, but the last time I pulled it out, it's showing all of my scopes sighted 6" high (which they aren't).  Seems like it has gotten knocked out of whack.  Is there any way to adjust it?

hey guys i guess the link didnt work but anyways its competitor, just google it :)
