1) ensure all screws are tight, adjust the focus ring at the ocular lens, and initially shoot from a bench rest if possible
2) bore sight the rifle on a 100 yard target
3) put up a target at 25 yards and fire 1 shot to ensure you are on paper, adjust the scope as required to be on paper
4) fire 1 shot from 100 yards
5) mark the bullet hole so it can be seen through the scope
6) set the rifle on a rest so it cannot move with the cross hair on the bull
7) without moving the rifle, adjust the scope until the cross hair covers the bullet hole
8) fire a 3 shot group to confirm zero
9) fine tune the adjustment as required.
10) if the scope is new, check to see that the POI does not change as you change the power setting of the scope.

assuming the rifle has a freshly mounted scope (done correctly)
- take bolt out of rifle and set rifle in rest, aim down the bore at an object downrange approx 25-50 yards away, then adjust scope until it is looking at same object
- fire a round, adjust scope towards bullseye, remember that you will have to move scope more than usual due to the closer range
- get rifle close @ 25-50y and then set up to shoot 100y
- fire 3 rounds then adjust scope to get it to hit where you want, usually +2-3" @ 100y with a 270 for a good trajectory out to 300 yards

" Our " ??? How many of you in on this XCR consortium ???
This gun going to be used for varmints gun or big game ?
Handloads or factory ammo ?
What brand/bullet/bullet weight ?
What is your anticipated longest shot / at what game ?
If in doubt, 130 grain 270's sighted in to strike 2-3/4" high at 100 yards
are a pretty deadly bet on deer-sized game right out to 300 yards.
About 260 yards will be "zeroed" for a rifle so-sighted.

Buy the best quality rings and mounts you can find.
Remove the cover screws for the bases. degrease the holes, degrease the mounting screws for the bases. Use some light duty Locktite, or finger nail polish to secure the screws in place, tighten screws to the perscribed torques as provided by the mounting hardware manufacturer. , if using turn in rings with dovetail rear adjustments use a long piece of 1" EMT or dowel to align the rings with the bore line. Lap your rings.
Install your scope, and tighten the rings evenly to prescribed torques.
center the windage and elevation adjustments.
Do a poormans bore sight as discribed above (looking through the bore)
Sand bag it in and get it on paper.
If any part of this is foreign or sounds totally new to you, get someone who knows about the above mentioned procedures to do it for you.

This gun's for my dad and myself. We will use it for big game and we going to use 130 grain and sometimes 140. Winchester ammo. About 100 yards.
We already installed the scope properly, but thanks anyways
. I'll do the poormans bore sight then the rest. Thanks for the help guys.We were going to zero it last week but it was too windy.
I disagree with the 25 yards thing unless you are going to put up a big honkin peice of paper at 100. I with a spotter, pick out something at 200 yards onthe berm and in three shots or so when I finally hit it, I know I will be on paper at 100. It's two easy to be off a bit at 25 yards and then end up off a 8/5x11 inch piece of paper at 100.
The same on all the other advise on good rings and scope focus etc.
