What's the best way to sight in a scope? I don't have a bore-sight or laser and I'd like to know the most efficient method of getting the hole to match up with the cross hairs.

Yeah, it might be a common sense question, but I'm hoping to lean something new here.

Thanks.

What are you sighting in? If you got a clear view through the barrel, you can look at a target and sight the scope to the same place to get it near zero

here you go: This was from another thread, but exact same concept:

here is what you can do:

1. Remove BCG (or bolt, if bolt gun)
2. Set upper receiver on rest, bags, whatever. Make sure it is secure.
3. Look through barrel, set it on target at known distance (preferable 50 yards).
4. While making sure the upper is secured, adjust scope to the same spot the barrel is centered on.

This is how I do it. Except I add a spotter to tell me where I'm hitting if it's off paper.

Mechanically zero the scope
shoot 1 round from a solid rest.
without moving firearm, adjust scope until crosshairs are aligned to fired shot.
fire 2nd shot to confirm
done...

Thank you, will do.

This assumes they can FIND where the 1st shot landed.
A simple bore-sighting will get them on paper to be able to do that 2 shot sight-in.

Put a large plain piece of paper with a 1/2" dot in the center at about 25 yards away on a target backing.

Sight the gun in there and get your Windage adjusted. For a regular scoped rifle, have it shoot 1/2" low of the dot. Then go out to 100 yards and fine tune.

Too many people start out at the 100 yard line and waste a lot of ammo zeroing. You can be zeroed in a few rounds at 25 yards.

Also remember when zeroing a 1/4 moa. click scope at 25 yards, 16 clicks will move the impact 1 inch at 25 yards .

A 1/2 moa scope will take 8 clicks to move 1 inch at 25 yards.

An AR-15 A1with iron sights(1moa per click or an A-2 1.25" per click) It will be about 4 clicks to move 1" at 25 yards.

This will get you zeroed quicker knowing the correct movements of the sights at 25 yards.

Hope this helps.

I put a golf ball on 100 yard berm. Shoot at it (from the bench, off a sandbag) while a buddy tells me where in the sand the round actually hit. Adjust crosshairs. Fire again. At this point, if I did my clicks right, I am close. When I hit close to the golf ball, it means I am on the paper. I switch to paper and with three more shots i'm in the black. I once had to sight in ten rifles in one afternoon for a "round-up" article. I couldn't have gotten them all on paper so quickly without this method.

I thought i was the only one who did it this way.I do the same thing i just find and object about 75 yards away and go at it.Has been close everytime too

This is the ticket and can be done at any distance. I taught my stepson how to do this when he was 14. His first shot was about 4 feet off. His second shot was 2" under a clay pigeon. He broke the bird with his third shot. It was also his third shot ever at 1000 yards. I was extremely proud of him.

This is the method in the "shepard Scope" ad. the keys is that there be NO movement in the rifle when you adjust those cross hairs.

Here's a couple of articles of articles from http://www.chuckhawks.com that I found helpful when I was first sighting in my hunting rifle.

Five rounds, the last two just to confirm that I really was dead-on in three shots.

Thank you gentlemen.
