Saves you the trouble of squinting through the bore (which is certainly difficult for many guns to begin with), but other than that.... don't see that it guarantees you will be sighted in any better. If you can't see well enough down the bore to boresight, then yes, it could be help.

 

I use one of the laser sighters that fits in the bore. This little device has saved me a bundle in wasted ammo. I can usually get the bullet within an inch or so of the bullseye by using the laser sight in device first. After you use one a few times, you kind of figure out exactly where to place the laser dot in relation to the crosshairs and it even gets easier then. I also find the laser sighters handy for verifing your scope after traveling to make sure it is still on target.

 

thats what im hoping jodum .. the product im talking has the potential of using sigt line or the same principle that allows the hubble to focus on a asteroid poo koo miles away..so the potential is there.
the object being to save ammo an possiby make it just an sight in with it,, to take one good scope ,, an switch it to several of your rifles without having to use much ammo.
one thing at what ever distance you set it at ,,it should be zeroed there if the product is as precise as it has the potential. to be..
im gonna investigate it some more. thanks for you guys input..
now im old fashioned .. i get something really right an i usually leave it..but im not tatally opposed to better ideas if they really work.. thats why jodum hands on recommendation is important..we ll see..slim

 

Slim, I am the worlds worse when it comes to swapping scopes around on my rifles. The laser sight lets me get them sighted in quickly. I would not hesitate on making a reasonably close shot with just using the laser sight for a setting in a pinch. Sure beats trying to look down the barrel with bifocals....

 

me too bifocals an all..

 

I'm 51 and wear tri-focals. I'm not very experienced in this compared to the fellows in this forum, but I've now bore-sighted 4 scopes. I've done them all by "eye"..... simply because I'm too cheap to buy a laser bore-sighter. Knowing what I know now, I probably never will buy one.

I put the rifle in a shooting stand, remove the bolt, sight through the bore on a can about 60 yards outside my side shop door, and adjust the scope to it. I have yet to be more than 9 inches off the bullseye at 50 yards (that's the Maximum on a Bushnell I put on a .22....... most are within a couple of few inches). What I do first though is adjust the parrallax (is that the right word?) of the scope before ever mounting it on the rifle. I have a cardboard box about 4" deep, 16" long, and 4" wide that I cut two "V" notches in. I set the scope in there and find a target about 50 to 75 yards away. Then I rotate the scope 90deg and see what happens to the point of aim. I adjust the scope (adjustments are backwards [reversed] from when sighting in at the range) to where the point of aim doesn;t change much. I never got one perfect, I just adjust it until it's within an inch or so no matter how I rotate it.

I figure I won;t ever need a bore-sighter unless it's for a rifle where I can't look down the bore from the breech.

 

i know where you coming from stretch.
now im confused .. the dope i have on it is it get you within 2 inches..
now the apeal of it to me is the exactness of a lazor beam..
it should be the shortest line possible from point a to point b.. in other words perfectly strait..assuming its not deflected , reflected or otherwise interfered with...this should be the case at 25 yrds..now if you have taken time to set your scope up right.. the same strait line should be from rifle to zeroed impact.point..
i can t see a reason for there to be any two inches alowance for error..
now i ll grant you the bullet doesn t exactly follow that strait line ..
but its impact point is where that same strait line will impact..
so why is there any error allowance.. mabe i ll see when mine gets here..
now a scope can be zeroed even if its not set up properly..so this would account for error.. but mine is i think..so its gonna be interesting to see if not dead on using this lazor... why not... not trying to be mr. smarty britches here but i just wonder if the real potential is realized by most user.. we ll see. mine might be 5 inches off. that would be bad. slim
now i know next to nothin about twist .. could be there,, that the allowance for the lazor error is found..

 

You can have the scope exactly in line with the bore. BUT - that does not guarantee the barrel will put the bullet where the scope points. Barrels flex and vibrate as the bullet goes out, plus there's a bit of an effect due to recoil.

As far as guaranteeing the accuracy of the method - the adapter cannot fit every chamber exactly. It should be pretty darn close for most of them, however.

 

yea mike i reckon you got a point .. it will still be a useful tool mabe..
just seems like the potential of it oughta take the guess work out of it.. but facts is facts i guess.. it ain t after all the hubble is it. slim
ps it just occured to me i can see how accurate it is right off. put it in my best 06..
if the light don t hit right where the hairs cross its off cause i know this guns on..that is if my thinking is clear on this..

 

The laser bore sighter will work on virtually any rifle,muzzel loader or shotgun and they are a real time/ammo saver. Most guns can be sighted in within a few inches. A case specific laser sighter is limited to that case. A bore sighter can be had for as little as $40.00 at Walmart.

 

This is kinda relevent to your thinking about the laser slim 60.

I had (and have) access to a product called "beamhit" or similar. It is a laser device that fits into the barrels of several diameters. Is for dryfire practice.

Inertia of hammer(or striker) causes this thing to emit a laser pulse. A electronic target then scores/counts hits. The "pulse" of laser light does last long enough for visual feedback to allow for you to correct your point of aim.

I found it to be good for indoor practice(mostly for trigger control and sight picture).
It DID NOT hit to my sights with real ammunition though! My hand, the twist and recoil of LIVE FIRE was different for me.

I've not used a laser on a rifle so I can't coment.

thanks brothers ..live a little, learn a little. slim
ps i think ive figured a way to make a case bore sighter work in any caliber..we ll see when it gets here..

 

i wanted to try this before i posted it.. the bore sighter cam in..
it turns out what i need do since mine are a good as i can get them is make a drawing of the crosshairs an keep it with each guns info.. that way if i put on a new scope i justput the red lazor where it is on the paper ive recorded for that gun.. then of course fine tune it.. they are almost perfect as to lazor being true .. the variable being how much high its zeroed ..
now if any have this type sighter jb weld a flat washer to the base
of the case[keep the weld as thin as a layer of paint....then i have some super magnets shapet about like an flat excederine..stick the thing on the crown of any rifle ,,an its as true as it is in th 06 that its meant for..i might add these magnets are strong enough to pinch a blood blister ,should you get a little bit of finger caught when two come to gather..i think i read that they come out of old computers.
in any case this would have saved a lot of time an money if id had it
over the years..its promise is to allow you to start no more than 2 inches off an fine tune from there..i believe it ll be a good thing to have. slim

 

yall have a good night now.grin

 

I never tried one of the case style lasers because I was too cheap to buy a separate adapter for each family of chamberings. Instead, I got one of the LaserLyte brand muzzle bore sighters which comes with plastic bore collets to adapt it to different bore diameters. They're never quite perfectly on, but as Mike pointed out, there are errors imposed by the bore being imperfectly straight or by the barrel flexing or there being bending moments due to asymmetries in the gun construction that will make even a perfectly bore coaxial beam be off the POI at least a little. Mine usually gets me within an inch at point blank range (35 yards or so on many of my guns). That's close enough to put a bullet on paper at 100 yards, and that's all that's needed.

I also have a BeamHit from aways back. I don't have it with me where I am right now, but I believe the switch on mine has a position for a continuous beam for sight setting.

 

i aggree with everthing you said.. now ive altered my case sighter so it now works both attached to end of barrel or in the rifle chamber..one factor ive notice whe in the chamber..if you turn the case it will create a different point where the lazor hits..
this tells me theres to much allowance for error..this thing could be made much more accurate..
on the front of the barrel its still got a variance..
so i got to say ...done with real precison it could in my opinion ,,be made to put the
rnd in the size of a rnd hole.. but it probably cost right much an ,,lets face it... it gets it close enough to finish easy..heck jus making a shot at 50 yrds an adjusting aimpoint over to impact point ,,can if you lucky put it on the money..
perhaps done right this thing could cause future gun owners to lose simple sight in skills..jmo

 

hard to admit this but my sight mark case bore sighter is apparently just junk.. nothing on it held up.. it finally got so the light would be on but not focused on the hole in the end of the sighter..
i should have just let it go or gone for the 100.00 sighters. but who knew..consider yourself warned .. nuff said..made in china by the way..
i could tape my lazor pen to the barrel an get more accurate than this turned out to be..live an learn..
yep i know i just made the whole thread a waste of time

 

Just dont forgt to remove it from the barrel before first/last round goes off.
