Subject: Bushnell Laser Boresighter
HI, Just recently purchased one, is the brass diode supposed to be centered or offset a bit, the one that i have is not centered? Plus only can see the laser about max 8 ft away? At night? am going to try new batteries, but this is supposed to be new and still in the pkg, got it off e-bay any info would be greatly appreciated. Thanks. Bob

I just took the above pictures in hopes that they can answer your question about the diode being off center. As you can see mine is not 100% centered, but it's close. Click on the pictures to zoom in. It does sound like you need a new battery or something is wrong with your boresighter. I just tested mine and the red dot was very visible 60 feet away (indoors).
Tanner, thank you very much for responding, the info was great, and yours is little closer to center than mine, but can work with it as long as i can see the laser dot. Took the batteries out of it last night and reinserted them today, can see about 15 feet away so am pretty sure it is the on off switch which may be causing a power drain, will pick up some new batteries and try it, Thanks again, Sincerely, Bob

The Boresighter can be adjusted to be more accurate. Drill a hole that it just fits into in a block of wood. Put the sighter in the hole and clamp that block in a vice so the laser dot is projected on a wall about 10 feet away. Put some paper on the wall. Now rotate the boresighter until the dot is at its highest point. Mark the paper with a line at this point. Now rotate until the dot is at its lowest point. Mark another line. Half way between the two lines is dead center for the boresighter.There are 4 centering screws on the laser end of the sighter that the little Allen wrench that comes with the sighter fits. Loosen the screw closest to the direction you wish to adjust the laser to bring it to dead center. Tighten the opposite screw. Repeat this a bit at a time. You may have to adjust the other screws in the same way. Once on dead center rotate again to check. Be careful not to move the wood block or the vice. Note boresighters are not meant to sight in a firearm. They are just meant to get it close so it is quicker and fewer shots are needed to do the final sighting at the range. Roger

I just purchased a Bushnell laser boresighter for my son's 30-06. I have a .357 Colt Python and want to sight it in as well. I have found the tip that matches the gun's bore, but after turning the laser on, it is well below what I thought was dead on center. What's the best way to sight this in before I make a major mistake of changing the gun's original setting. Ken
Response - Ken,
I have no experience with boresighters and rifles so I can offer no suggestions. As for the handgun, have you tried..
- laying the gun down on a table top (with the boresighter installed and "on") and pointing it towards a wall.
- mark the wall with tape where the dot shines.
- holding the gun firmly with one hand to keep it from moving, rotate the borsighter within the barrel.
- If the dot moves off the tape on the wall in a circle or ellipse then there is something wrong with the boresighter.
- If the dot stays on target then I would feel confident to make the sight adjustment.

Using bushnell laser sight, can you give me DETAILED instructions on how to use this laser to set scope @ 100-200 yards? last year, i missed 2 good ones. i ain't doing something right??? please help!!! Robert
Response - Robert,
The Bushnell laser boresighter that I bought was very inexpensive (cheap) but it did a good enough job for shooting at an indoor shooting range at a distance of 20-25 feet. I don't think I would trust it for long distance shooting. You may have to buy a more expensive and better boresighter for that. Sorry I can't give you instructions on how set the scope for shooting long distances.
