Laser boresighting - any use?

[meles meles]

There appear to be several reasonably priced laser bore sighting systems currently available: some are a probe that that slides into a barrel, others cartridges containing a laser that is chambered like an ordinary cartridge. Have any of you oomans used them, and do you recommend them? I can imagine they are useful for checking azimuth, but given that a projectile (neglecting air resistance) has a parabolic trajectory I'm not sure how useful they are for range...

Useful if for some reason you can't bore-sight - i.e lever-action rifles but, bore-sighting is quicker, more accurate and free!

Totally agree! Tried one but got different results each time and nowhere near as good as bore-sighting.

I had one as well and could never get a reasonable result from it so it went on eBlag. I much prefer to level the 'scope and then bore sight by eye at around the 400-600 mark, not an option with an under-lever but works for others

Hmm, the sight and the bore may be co-incident at the set range, but surely the bullet goes where gravity dictates?

Bore and laser sights are best suited for windage only as the distance where point of aim and point of impact meet is usually too far out to allow sight of the laser spot however the reflective bands on traffic cones work well as a sighting mark...

I use one when setting up my chrono, boresight on the target , put in the laser, set up chrono using a bit of paper to see the dot. Ensures you're shooting through center at right height and saves a couple of minutes.

OK. I will say it before anyone else does, it also saves a couple of Chronos.....

Any sort of sighting-in aid is obviously only to get you 'on paper' in preparation for proper zeroing..... its not intended to simulate bullet drop in any way.

You can bore-sight a Marlin as the bolt comes completely out......
