Laser bore sighting

So my question is this: If you laser bore sight iron sights, theoretically it should be perfectly accurate right? I know with a scope you need to finish the sight in on paper (to compensate for the mounting height of the scope), but I think for iron sights there should be no need...right?
 
My opinion: Any bore sighting tool is good to get you on the paper .... but after that proper zeroing requires shooting !

Personally, when I'm hunting I like to have the peace of mind knowing I can hit where I'm aiming, and nothing but actual practice will tell you this.

Laser bore sighters are also handy to have in your hunting gear ..... after you sight your rifle and your happy with it, re-check it with the bore sighter. Then take note of the difference ( if any ) from your actual point of impact to your laser tool indicated POI on a card. Then if your out hunting and you take a tumble, bang your scope, etc. it takes just a minute to re-check with the laser tool, referring to your notes to see if anything has changed.

joe-boy has it right. Any boresighter is only supposed to get you close. You can do just as well by putting the rifle in a cradle and looking through the barrel and scope and lining the scope up to the center of the image through the barrel.

I would never rely on one except to get the rifle close. They certainly aren't repeatable enough to use to quickly recheck your zero.

I'd have to disagree with this. I find the laser sighters, at least the one that I have, are way more accurate than the old-style ones in which you looked through the scope at a grid pattern. I can almost always use them to get the first shot to within three inches of POA at 100 yards. If you carefully laser-measure a range of 50 or 100 yards, and then duplicate that in the field, they will put you within the same range of precision when checking your zero in the field. Granted, not perfect, but it gives you good indication of whether or not there has been a change, expecially since you can also see if the displacement remains the same left, right, up or down.

I'll always check my sights after flying with my rifle, or even driving a long distance to camp. But the laser in my pocket can restore a good deal of confidence if I take a tumble in the field, without actually firing a shot.
 
So I tested this out. Used the laser bore sight and set up a new pair of iron sights on my lever 30-30. The thing was bang on when I test fired it. Didn't have to make any adjustments in the field. I can see it needing to be re-zeroed for range on a scope, but for irons the thing works mint.
 
Not perfectly. When I sighted in my rifle I did it with boresighter at 25m and then shot it, adjusted scope, took it to 50m, adjusted, to 100m, adjusted, done.

... then 200m adjust it and done. There is often more correction needed if you shoot the further ranges.
For me a laser sighter is just a tool to get close, I could never trust the rifle with out having shot it.
 
ya totally, I understand the scope needs to be adjusted. All I'm saying is that with iron sights, it works pretty damn good. And if you have to adjust your iron sights, you are likely looking at that wrong.

Range was limited to 100m, couldn't shoot further than 100. Last group of 3 shots was pretty tight with all 3 holes touching a dime coin placed over. Good enough for me. Scope was (and still is) Nikon with BDC.

Wouldn't a bore sighter have more to do with where the group was, not how tight it was?

I bought a laser sighter and after much aggrivation and swearing, I discovered that the machining was faulty, and if the laser was rotated in the bore, the red dot moved in a circle on the target and I mean a large circle.. I returned to the store and they gave me another new one. Back home to try again...same problem...Back to the store with the gun in tow and it took 7 tries to find one that did not change POI on the target. These lighted "aimers" are to get the gun close and only firing the gun will give the grouping that tells where POI is. I certainly would not trust shooting an animal without finding POI of any gun ...open or scoped.
 
This one is awesome! Its very easy to use on any gun and gets you sighted almost perfectly without firing a shot, makes it very easy to dial yourself in at the range. The green laser shows up in daylight at 100 yards.

Also if you have a laser sight on a pistol use this for whatever range you want your lasers POI to be, shine it at the distance you want and just adjust your laser sight right on top of the bore sighters laser and its perfect.

I just have the basic bushnell one that you stick in the muzzle. It comes with a bunch of arbors to fit basically any caliber. Seems to work great. I've tested it on 3 rifles with iron sights and it's bang on.

Ha..Ha.. No Sir,It only help you to get your bullet on the paper,and than depend on what load the rifle likes and how good the shooter is.:D
 
I was thinking of getting the Cabelas one where you chamber the actual bore sighter.....but the one in the video above seems pretty dam good!
 
i have used all the different bore sighters at one time or another.do not really care for the laser sighters that go in the bore.have found the ones you chamber to be better.just wish they made them in more calibers.the one where you start with the 223 size and buy sleeves to step it up to larger sizes i think might make it less accurate.
 
The one that I use and have very good success with attaches magnetically to the crown of the barrel, with no intrusion into the bore. I am totally satisfied with its performance, but I stress that its main purpose is to get you close to POA with your first shot, which it does very well. I am not suggesting that it will negate the need to shoot your rifle to make final critical adjustments.

I'll check when I get gome and post the manufacturer's name...having a senior moment and can't recall it right now.:redface:
