General rule is to have it shooting 1.5 - 2" high at 100yards, then you are good out to 300yards without needing to compensate for drop, as it will be minimal within this distance with a .308 & 150g projos.
Also use a good rest, front and back to reduce the amount of human error. If you can get to a proper rifle range it makes things easier as there are benches to shoot off and set distance target stands setup.
If you find that your shooting isn't the best, I find it good to start buy shooting a box of ammo through my .22lr, helps settle things down (trigger control, relaxing, breathing, etc.)
To start if I were you and had no idea I d get someone to bore sight it. You can do it yourself by clamping it down and looking through the barrel to line it up on the wall on a cross or something.
Then look through the scope and adjust it so it too is on the cross or nail or whatever. Don't bump it or move it. Check through the barrel to make sure it doesn't move while you adjust the scope
Get that roughly right and you should be on paper at 25 or 30 mtrs. Fire two rounds at the paper see where they go. Adjust to get close as possible to the vertical line first. If it hitting right at the bottom or top bring it up or down a little to allow you to tune the vertical first. If you get the vertical correct it should need none or very little further out. If you cant get it to stabilise on the vertical you gonna need to check mounts etc and scope alignment. Don't overheat so if the barrel gets hot take a break. Stabilise the vertical first if you cant may as well try to figure out where the problem is. No point proceeding itll never be right.
Once vertical stabilised set horizontal to be couple inches above the horizontal and that should get you on the paper at 100 . You can go to fifty first look down barrel and through scope to see approx. whats going on.
That's gotta be enough for you to be starting with. Sight it in over a few days if possible as it just will get better every little tweak.
Cheers Happy
As above, bore sight shoot at 25 or so get it close zero couple inches high at 100.
Some scopes won't move as much as they say they will so be aware of that.
And most but not all left or up or whatever means it will move the impact that direction. Some are backwards :rolleyes:

Have the front rest under the front of the stock, not under the barrel
This is good advice.Quote:

A quick method I started using a while ago now ,is once I'm on paper.Shoot a 3 shot group ,then measure
from the center of it vertical & horizontal.The inches equate to clicks MOA on your scope .
1" = 4 clicks at 100m or 8 clicks at 50m etc. Saves time & ammo @$2+ per shot money that can be spent on other things.

However not all scopes are decent.
I have a vx1 that moves not quite twice what it should.

And I've just put a VX1 on my new T3 ,will see what happens this
weekend when I sight it in.
Sight it at 25m might compensate for the excess movement.
You might get lucky and its good.Quote:

The Bushy Banner on my .22 is the same, its basically 4 clicks per 2"! Holds zero fine though.
I just sighted in my 308 and 300wm this afternoon, both new rifles and new scopes.
It was a piece of piss.
I bought one of those scope levels, the one that you sit the small bubble level on the elevation turret and clamp the other bubble level on the muzzle end of the barrel. Did this at home.
Went to the range and set up the flouro target ring sticker at 50yds, bore sighted the rifle, fired one shot which got me on the outer ring and then made slight scope adjustments to get in the bull.
Then set up another flouro target at 100yds and cranked out a shot which was a couple of inch's low, I must have continued firing about 5 shots just to see what sort of group I was getting before adjusting the elevation turret so I was approx 3" high at 100yds - That will be good for say 250yds which is max distance I'll be dropping animals with next week.
Repeated the above steps for the 300win mag.
Getting bloody good groups with shitty ammo, was using Highland 308 150gr then once sighted in pumped a few of those Bitterroot Amax 168gr's re-manufactured rounds and got sub moa.
So I'm all set.
Sighting in is simple simple! Boresight it as suggested above, but dont worry about any fancy clamps etc, just cut a "V" in to the end of a cardboard box and sit your rifle across the box, pistol grip fitting tightly in to the "V" Once boresighted fire 1 shot over a good rest at 25 metres, change scope to bring exactly on to centre, fire one more shot, repeat. You should be able to get it right on the button at 25 metres with 2 or 3 shots. With most sporting rifles in 308, this should put you about 3" high at 100. Once you have it centred at 25, move out to 100 and fire a group, 3 or 5 shots, then adjust your scope to bring the centre of the group to where you want it. Most 308's doing approx 2800fps need to be 3" high at 100, for 3" high at 200, zero at 250, 5" low at 300. Using this method I have been lucky enough to only use 7 shots to sight in the last 3 rifles I have scoped - 2 shots at 25, and then a 5 shot group on the button at 100.
I did get lucky I think or did you strike a crook scope.My VX1 LR reticle version works fine.Quote:

No I think its as its meant to be 4 clicks to inch at 100m.VC
Took a full turn on elevation to get it on paper & same again to get to bull.
Only minor adjustment laterally of a few clicks
