Hi all. Does anyone have a recommendation for a good boresighter tool? I want to be able to get my scope as close to zero as possible, with the reticle centered, before tightening everything up and firing. I need to be able to use it in my home and it would mainly be for non-bolt action rifles of various calibers.

Thanks in advance.
-Jeff

I rely heavily on my Leupold Zero Point boresighter . I mount the scope and center its reticle on the ZP's "reticle" in the comfort of my basement. Then, whenever I go to the range, I go straight to the 100 yard range and sight in, usually on an 8.5 x 11 target I've printed off the internet. I've never had to take more then three shots to be zeroed and the most I've been off (so far) with my first shot was 3 inches right and about the same high.

It took a little getting used to in the beginning and sometimes its reticle can be hard to see in bright sunlight, but its main value for me is getting me on paper with my first shot.  So far it has done admirably well.

X2 on the Leupold. It is so small you can carry it with you and if an accident happens it only takes a couple of minute's th be back on site. It makes swapping scopes a breeze. It usually is within 1" at 100 yds. My Zero point came as a gift when purchasing a Leupold scope from SWFA. Thanks again SWFA.

That Leupold sounds like the way to go, I have a low budget model from academy. It has a bunch of little O-rings and other poop to deal with and doesn't like auto-loaders at all. It does a decent job and works indoors, but it's not really user friendly and has too many pieces in the box to ever take outside.

The proof to me was when I had to swap scopes on a PD hunt. After setting the scope with the Lepould Magnetic sightin tool I was hitting PDs out to 300 yds without any other adjustments.

I use the Leo also with great results. My son had one rifle (Savage) which it did not work on. It would be abot 18" off at 100 yards. I don't know why this happened but I suspect the crown was not cut square to the bore. The rifle was accurate (1.5 MOA) but the Leo would not work on it. A laser boresghter that fit in the bore might have been better for this particular rifle.
Works great on everything else!

I use the free method. Take your bolt out and look down the bore. That is if you have a bolt action.

typically referred around here as the "cheaptrick" method, it works great! i can usually have any of my bolt rifles zeroed at 100yds with 3 shells using this method.
doesnt work for semi autos though.

I used the "look through the bore" method on my AR.  Popped the lower off, pulled the bolt and got very close to the bull at 50 yards.

I talked to a gunsmith at Gander today and he said the Leupold Zero Point is the only tool he uses for boresighting.  Said it's easy to use and quick.  I think I'll order one.  I need it for rifles that can't be boresighted by eye.

There are good ones and bad ones.  Best results are achieved in very low light conditions.  When I get to go to the laser lab, I can use an extremely high power, tight beamed instrument that allows me to boresight at 100yards.  (.5in diameter dot at 100yds)  That system is generally right on first shot, sometimes no further adjustment required.  So far I have been unable to take it home.  
The "cartridge type" in low light out to 50 yards are very good, usually one or two shots for zero.  You can generally find one producing a 1inch or small dot at 50 yards.  At 100 yards the beam diffusion is large enough that it is not highly accurate, but as good as most collimators.  50 yards seems to be the best accuracy for those.  
Key to laser boresighting is ensuring you are not getting reflections off the bore.  

I have a few different kinds of the cartridge types... every one seems different.  I don't recommend the arbor types.  Too much alignment time for me.  Spending the amount of time required for set up of one of those should provide greater accuracy, my opinion.  
The technology is available, I am not sure the marketplace has demanded it enough to get where we want to be with this type of boresighting.

Mine is the laser in the chamber type with all sorts of adapters and o-rings. It works but I hate all the ritualistic stuff you have to do to make it work right. "It's worse than a Catholic Funeral" It's got plastic shells from .223 up to .416, 2 different rods for different caliber ranges. 7 sets of o-rings, a target, and a battery pack with wires to the metal bullet that screws into the plastic bullet. "pretty much everything but 8 maids a milkin"

I'll trade it for some magic beans and a link to the Leupold. Thumbs Down

I bought the laser that fits into a .243, 7mm-08, and .308 for my Weatherby in .243.
 
It worked great on the one scope I've mounted. After lapping the rings and installing it the cross hairs of my 6x40 Burris were almost dead on so I took it to the range without further adjustment and it was in the 5.5" ring at 100 yards right off the bat.
 
The only downside is that you have to actually remove the battery to turn it off and on.
 
I live in residential Silicon Valley where folks get nervous if they see you pointing a rifle around and I wanted to maximize my time at the range.
 
I've never owned a bore-sighter.
