Looks very similar to the one I have and I use mine for everything from 22lr on up. Just pick the right size tip to put on the end, stick it down the barrel, and adjust your scope till the crosshairs are on the red dot. Won't be perfect, but should get you on paper at 100yds.
Those who must raise their voice to get their point across are generally not intelligent enough to do so in any other way.

Sounds good. Until I saw the video I thought it went in the breech end (like the ones that are fitted in dummy cartridges) and it did not look like it would fit.

I am curious, why do you want one? Unless you are changing scopes out a lot, I don't see the reason to buy a bore sighter. You can look down the barrel and sight your scope in pretty close. You would only be saving one or two shots while sighting your gun if after that with a bore sighter.

And I find it hard to sight in the older Weavers that I like on my older rifles: Also, without a good way to clamp my rifle down it is hard for me to sight through the bore.

It Doesn't Work! Don't waste your money! Pull the bolt out of your Winchester & look down the bore. Line up the bore with a 6" target @ 50 yards. Then adjust your scope to line up with the Target. Works Every Time..... I can sight in ANY of my bolt action rifles within 3 or 4 shots using this simple method. I'm always amazed at hunters who have their gun "bore sighted" at the dealer they bought it with, then go hunting, thinking they are sighted in. Then they wonder why they miss

Chlin is right though.
Bought one of these boresighters to try because it was like $10 and I find it close to useless. I do much better with the looking down the bore method.
My kids like to use it as a laser pointer though.

Any sort of bore-sighter (or collimator, if you prefer that term) is useful for more than sighting-in. Obviously anybody can bore-sight their rifle at the range before touching off any shots, but a bore-sighter helps when mounting scopes, by making sure the scope's center is reasonably lined up with the bore.
This not only provides the maximum amount of adjustment, but scope adjustments work more accurately and repeatably when the scope's lined up with the bore. There also can be parallax problems if this isn't done.
I was once lucky enough to have a workshop with window where I could aim a scoped rifle in my bench-vise so that the scope (or sights) lined up on the tip of the neighbor's roof. That would bypass the use of a collimator for mounting scopes, but I've yet to have the same sort of set-up since--and most people don't.

Boresight at home, sight in by shooting at the range.
But you knew that.

My closest neighbors house is 5 miles down the road, and I couldn't hit his house with a 50 cal Barrett

Last Fall I zeroed 3 rifles with new or different scopes on them. I bore sighted them by looking through the bore. These are the 50 yard targets with the 1st shot fired. Shot #2 was at 100 yards. After making a few minor adjustments the 3rd shot was exactly where I wanted it at 100 yards. Only then do I start shooting groups. Can't see where one of these devices would ever save me 1 minute of my time or 1 round of ammo.
Most people don't really want the truth.
They just want constant reassurance that what they believe is the truth.

I was motivated to try a bore sighter because for whatever reason I could not get on paper with my 1949 Weaver K 2.5 on my Model 70 This internet article is interesting: Bore sighting-How High at 25 feet?

I use the looking down the bore method and it gets me on paper at 100 fine. Not as close as JMR40, but close enough.
I have considered buy a bore sighter to keep in the truck when hunting. If I drop the rifle I was hoping that the boresighter would tell me if I had a radical change in zero. You folks with boresighters.. is this practical?

you know what a lazer bore sighter is good for?? setting up a chronograph. I just take a target and put it behind the chrono and its a snap, just remember to take it back out.
as for sighting in the scope forget it. I have one of the old school bushnell bore sighters that uses the different size spuds and you can see a grid, this would work great sometimes and others I would totally be off the paper. I have a house behind me that is about a 100 yards away one of the lights on the side of the garage works great to line up with bore with and then the scope, this is mounted in a cheap lyman gun vice. works great everytime.

Something that I have never been able to make proper use of is a reticle leveler. (I have many faults; this is but one of them.)

nsaqam - thanks for the suggestion. My problems always seem to revolve around these things: knowing whether or not I have the rifle square with the world, if I do believe that I have it square with the world finding out that when I shoulder it comfortably, it is no longer square with the world, and tightening Weaver rings. (That probably just indicates how hopeless I am.)
