Thread: Bore sight Lazer way off when rifle is zeroed

Hey team trying to get my head around this one, when I bore sight my rifle with the Lazer I get the scope pretty much bang on. Take it to the farm and puts some rounds through it at 100m then 50m and I'm way way off (about a ft left and high). I spent some time getting it to hit paper then get it zeroed. Put the Lazer bore sight in it when i got home and at 20m the dot of the Lazer is about 3 inches low and right of where my cross hairs are.
Rifle is a Ruger American .308 w/ Burris E1
Is this normal or anything you guys have come across before?
Cheers

The lazers are rubbish bro

Good boresight should have you on a4 paper at 100Y

edit to add they are only good on sharks in movies

I’ve not heard much good about laser bore sights. Never used one though

Waste of time. I use a colometer and that gets it pretty close but still need to shoot it to fine tune it.

Bore sight lasers are a sales gimmick and a complete waste of time.

Never heard of a colometer. What is it?

Unless your using your laser boresight at the range your shooting at it will be miles off.
You need to work out how far below the cross hairs the laser will be at your laser zero range.
Last time I used one, the laser dot was 3" low and .25" right at 10m but pretty close to bang on at 100m

I've got 1 that fits in the muzzle and it was way off when new but it is spot on after I tuned it. I put in the lathe and rotated the chuck to show a big circle on the wall, simply adjust the 2 screws to get the dot in the centre of that circle. Spin the chuck again and the dot should remain on the same point.
This doesn't allow for ballistics but has got every rifle on paper first shot.

Cheers everyone. Will get rid of the lazer and just roll with how it's zeroed at the moment.

It goes in the muzzle end of rifle and has what kind of looks like half a scope on it when you look through scope you can see a grid that you adjust scope to. Some people seem to have a knack of bore sighting by looking through barrel but i suck at that. Tried a laser and that was shit colometer works for me

Colometer got my rifle about 2" from the centre of the target at 100m. Definitely a good product

Identify your target beyond all doubt because you never miss (right?) and I'll be missed.

it will at best get yo on paper and save you a few rounds sighting in thats it

They are bloody useless. I've always eyeball bore sighted and can get on to the target at 100yds with first shot. Although @No good names left has nailed the issue with them. If you have one, roll it along a flat surface and watch the large circle it draws on a wall.

To bore sight I use an insulator on the power pole in the neighbours paddock, about 100 metres away, as the target to bore sight. I then add a few clicks of elevation and I'm good to go at 100yds.

However, I do own a laser but the only reason I bought it was to speed up setting up my optical chrony, when I had one.
Otherwise I'm pretty adverse to putting anything in the muzzle.
I nearly had a disaster once when setting up my chrony, I forgot to remove the laser. A the last minute I realised the laser was still in the muzzle. And by last minute I mean I was behind the rifle ready to chamber a round. After that I developed a practice of removing the laser from its plastic box and then sitting the bolt on top of the box in the laser's place.

I've also got a Leupold collimator. Long since discontinued by Leupold. I wonder why. It attaches to the muzzle magnetically. It give a different result from rifle to rifle so not reliable either. And no, my muzzles are not on thepiss.

I alway chuckle to myself if I'm in a gunshop and a staff memebr is setting up a scope for a customer using a laser. Few boxes of ammo probably sold at the same time.

Forget the laser, just a cheap, rubbish gimmick.
Learn proper boresighting by taking ths bolt out and sighting down / through the bore, get it centred on your 50 yds bullseye. Hold the rifle steady in that position and adjust your crosshairs to match. Then shoot. With great luck you will have it good with the first shot. Usually though it's off, but close and a minor scope adjustment gets it spot on. Then check POI at longer distances, adjusting scope for your preferred zero.

The next thing to learn is once you have a couple of shots on the target, and if the shots are a wee ways from your aiming mark, position your crosshair on your aiming mark, and without moving the rifle, adjust the crosshair to point at the shots fired.
Be aware, it can be confusing, as the turrets will appear to indicate crosshair movement opposite to the arrows on the turrets.
Once near the desired aiming mark, adjust using the grid on the target, if using that type of target.
