Cobra 76 two 2,677 Posted November 29, 2010 Report Share Posted November 29, 2010 What's you favorite that you have used? Does anyone have any experience with one of these? http://www.opticstalk.com/leupold-zero-point-boresighter_topic1630.html I have one on loan to use on my rifles and get me on paper as close as possible. Ammo is expensive these days... Quote Link to post Share on other sites
sharkbit 109 Posted November 29, 2010 Report Share Posted November 29, 2010 i've used the end of barrel laser boresighters that have the different caliber arbors. They work ok to get you on paper. Only problem is they work best under indoor or lower light conditions. Quote Link to post Share on other sites
Mayor Al 41 Posted November 30, 2010 Report Share Posted November 30, 2010 I bought a 12ga shotgun-shell dummy with a bore-sight laser in it. Chamber the round and align your sights with the red dot coming out of the barrel and you are close enough! I have done it so that the sight is a hair-high at 25 yards (in the house/daylight). I want to check it at night in the yard for a 50 or 60 yard test...but it's raining hard, so I'll wait ! It was an easy task with that steady red light from the barrel to use as I adjusted the sight-aiming point. Those little Allen wrenches are not as easy to hold as they were 10 years ago though !!

Berzerker2 19 Posted April 11, 2011 Report Share Posted April 11, 2011 i've used the end of barrel laser boresighters that have the different caliber arbors. They work ok to get you on paper. Only problem is they work best under indoor or lower light conditions. Anyone know if there are green laser boresighters on the market? I use a red laser and I usually bring the guns I'm boresighting into the warehouse at my work. It's usually dark enough to get a good dot to show on the back wall.It's only about 25-30 yards but close enough for setting my scopes up for CQB situations. Quote Link to post Share on other sites
yakdung 2,926 Posted April 11, 2011 Report Share Posted April 11, 2011 (edited) I have the red version of this one and it is pretty nice: Good luck, Yakdung Edited April 11, 2011 by yakdung Quote Link to post Share on other sites
Koljec 37 Posted April 12, 2011 Report Share Posted April 12, 2011 any reason not to use chambered laser boresighters? Quote Link to post Share on other sites
Berzerker2 19 Posted April 12, 2011 Report Share Posted April 12, 2011 (edited) any reason not to use chambered laser boresighters? Well it can get expensive if you have multiple guns in different calibers. The ones I use have different size adapters that I can use to boresight from .22 cal up to 12 guage.

gtnichols 51 Posted April 12, 2011 Report Share Posted April 12, 2011 The bullet comes out of the end of the bbl so what better place to locate the bore sighter,.. of course the term bore sighter would run the length of the bbl Quote Link to post Share on other sites
racolqui 19 Posted June 9, 2011 Report Share Posted June 9, 2011 I have the red version of this one and it is pretty nice: Good luck, Yakdung I have had the LS-100 version of this for many years and used it o multiple guns. It has always worked great. I also have some of the in the chamber cartridge type.They work well but battery life seems to be a lot less than the LS-100. Quote Link to post Share on other sites
IndyArms 10,186 Posted June 20, 2011 Report Share Posted June 20, 2011 Personally, I NEVER use a boresighter... and I am willing to bet I can have anyone's rifle just about dead nuts at 100 yards within 7 to 10 rounds. If you are using a bolt action rifle, I just set the rifle on bags and aim it at a 50 yard target. It needs to be ROCK STEADY without touching it!! I then look through the bore with the bolt removed and put the black dot of the target in the center of the bore... Then raising my head a little bit I see where the crosshairs are aligned... I adjust the optic so that the crosshairs align with the sight picture through the bore... Once you are at that point... shoot a 3 shot group. Adjust your group according to the optics adjustments to get you "dead center" and shoot 3 more. If this is now on target at 50, move to 100 and fine tune the POI. If not... adjust again, and then move to 100 and shoot another 3 shot group and adjust accordingly at 100. With a Semiauto, its a little more difficult. but I just use a LARGE sheet of paper... ( like 2' wide by 3' high) see where the first 3 shot group hits... and adjust to center by having the rifle ROCK STEADY on bags... Put the crosshair on the point of aim, and while keeping the rifle ROCK STEADY... adjust the scope so that the crosshairs now touch the point of impact. Repeat as above with another 3 shot group, then move to 100. Remember that at 50 yards you need to move a scope TWICE AS MANY CLICKS than you do at 100!!! and 4 times as many clicks at 25 yards!!! If you are off a 2' X 3' sheet of paper at 50 yards with any optic... you have more problems than the cost of ammo to sight in... Always adjust the average location of a GROUP of at least 3 shots!!!! *NEVER* ADJUST after one single shot!!!! If your rifle will only give you a 2" group at 100 yards, without adjusting a group, you could be moving crosshairs all day long, trying to get it "zeroed" when you were just chasing errant projectile hits. Likewise, if you are shooting at 50 yards, you SHOULD be able to get a very small group to adjust... if you try with single shots... again... you could be chasing them all over the paper without ever really knowing where you are really hitting due to a large group size.
