Working with a used scope

I bought a clean Leupold 36-X off e-bay . It came yesterday and looks as I thought it would .
Now the question Would it be a good idea to center the cross hares or just mount it and go .

I,m thinking I need to adjust it to the middle of the adjustment first or make sure it is close .

Mount the scope on the rifle you bought it for, take it to the range and set up a target at 25 yards or less make sure target has a small black dot, then set up your rifle and make sure it is well supported,remove the bolt and look down the bore of rifle until you center the target dot in the center of bore! At this point hold the rifle securely or have a friend hold it and then look through the scope, and dial the crosshairs so they are centered on the dot. Next place bolt back in rifle and shoot a round your shot should be on paper, next make adjustments to get bullet to center on dot. If you are using this on anything but a bolt action rifle what I just described won't work! you will probably need a collamator!
 
Unless you are using a mount and/or rings that have some adjustability, I would just mount it (properly) and bore site it. If you take your time, and your barrel is straight, you should be on the paper. With my bench gun (custom action, top quality barrel), I can manage this at 100 yd. For lesser rifles, I start at 25yd. The trick is to get everything EXACTLY centered before the first shot. Many times when I have shown shooters how to bore site, they say they have the view of the target centered in the bore, and they do not. Take you time, and get it right.
 
Personally, when working with any new or 'new to me' scope, first I like to run the adjustments their complete travel a few times.
Then mount it up and just snug the screws, mount the bore sighter and run the adjustments again while watching the grid.
I've found more than a few problem scopes this way, before wasting a range day and a pile of ammo.

Vinny That is what I was looking for . I know how to mount a scope and how to bore site .
I do think I need to do whatever I can to see if this scope is working right .

Thanks KEYBEAR

Click to expand...

Once you get the scope zeroed you can check tracking by going up 4 clicks and fire a shot or two, right four clicks fire a shot, down four clicks and fire, left 4 clicks and it will hopefully return to same point. This will tell you a lot about tracking of scope but it tells you nothing about holding POI.
The only thing that tells you if a scope is holding POI is shooting a good group, if group is not good it may be the scope or it may be something else.

FWIW,
A "custom reticle/ repair specialist" told me not trust the last full revolution, otherwise the scope doesn't have to be centered.
Good shooting!
 
Remember this , even though you bought the scope used Leupold will still work on it, I send my 36's in at the end of each season and ask them to clean, inspect and check each one it cost me about 13.00 for postage and they aways send a note back on what they did. Great customer service, last year I had them change a reticle for me and I think they charged me 56.00. Good luck they are great scopes.
 
I agree with you Leupold service is good . I sent a 24BR to them 3 weeks ago .
I was told by a friend to never buy a used scope ? With Leupold it,s not a problem .
I will be sending this 36 in next week .

My Hawkeye bore scope has shown me that an in barrel boresighter is best left in the junk pile. A 25 yd tgt is just to easy to do.
