Bore Sighting Tools????

bobinwis
I would appreciate comments on any of the bore sighting tools that are on the market if you own one or have used them or seen them in use. Some have universal barrel studs, some have a number of adaptors that come with the tool, some use a magnet to attach to the barrel. Are the laser type accurate? Could I attach a target to the basement door and sight in very accurately with a bore to door distance of about 50 feet?

Thanks in advance, Bob

    A collimator is very nice to have and is an easy tool to use but some have a problem with errors. I personally have a preference for using the bore itself with the rifle clamped in a vise and sighting on a target about 50' away but that is the system I grew up with. I recently was at the range with a shooter whose scope had been collimated and it was off the paper at 100 yds, using the bore got him on the paper.

    Here's what I found using a Laser Bore Sighter. Without being able to begin at a minimum of 25 yards, I found the difference in the heighth of the sights above the bore of the barrel to sort of "confuse" the issue somewhat. If the imaginary line drawn when looking through the sights is in an equal plane with the bore, you will always be sighting slightly higher than the barrel. You can set the laser to converge with the sights at a certain distance, like 25 or 50 yards and then you can make the changes necessary to "raise" to 100 yards and so on.

    The problem I have had with the laser is it must be at least 25 to 50 yards to become accurate enough to be useful to me.....others might find this different, but that is my experience. At just 50 feet, most of the time I find the "red dot" to be below the front sight and not visible or useable to reference against.

    I bought a Leupold boresighter after asking around a bit. Its one of the ones with a magnet, for the end of the barrel. Ive used it on a pistol and a couple of rifles and its gotten me "on the paper" at 100yds. They are about $40. The place where I got it said that's what they use for all their store-bought rifle/scope combos... Pretty simple design and easy to use...

    I use the same methiod as D.Bryan, however I add a "Tool" to make it easier & a little more precise for someone that dosn't do it a lot.
    The "Tool" consistes of a fired case that has had the primer knocked out. Insert it into the chamber and look through the primer hole.

    Some guys like a mag full of lead, I still prefer one round to the head.

    I have successfully used laser-lytes in all kinds of firearms, from short handguns to rifles. Ironsights, scopes and even "red dot" sights. I agree with the "judge" above in that parallax adjustments do play an important part in using this tools. But their ease of use far outweigh this minor inconvenience, and most laser bore sighters I have used have proven repeatitively acurate. I do suggest using a "bubble leveler" whenever parallax sighting plane exceeds more than one inch, or at least a reasonable effort to maintain the vertical center line when adjusting the windage.
