How About Comments On Laser Boresight Devices


Registered Users do not see the above ad.


Lets get some comments on those laser boresighting devices.
I am talking about the kind with the expanding plastic tip and a tapered aluminum forward section that centers the unit in the rifle's bore.
What kind of correlation of first shot to laser spot do folks get with these?

I have been using a laserlyte laser boresighting device for several years. Wouldn't be without one. It has saved me a ton of money on sighting in a rifle. I can set a rifle with the laser boresighter and be on paper the first shot. I can also use it to check to make sure a scope is still on after bumping it. They definately save me a lot of time and money.

I think the last time I used mine it was off about 3 moa. Not too hard to count the clicks over from that. It sure took a lot less time than going through the eyeball bore sighting seesaw.

I suppose that's one thing those cartridge case-shaped laser bore sighters prevent. A suggested safety device I've seen described before is made by putting a half inch hole through a cardboard disc an inch and a half wide or so and colored orange. You slip the bore sighter through the hole. You see the disc in the scope to remind you the sighter is in place. You can still see the dot over the top edge of it.

I'm always a little surprised that people shoot them. Do they get on the gun and say: "Gee. I think I'll take a shot at that little red spot out there? It's right in my crosshairs anyway." Or do they turn them off, then leave them in? That would be a habit to break before it starts. It also makes a good argument for removing the bolt when you use one. Put it on a piece of paper on the bench that says, "take the bore sighter out before putting me back!"

If you get the muzzle insert type stay clear of the Bushnell one. Sent 3 back cause they were so out of whack .. I checked them with a rifle w/ sites and all were off at least 4-5 inches at 25 yds. Pretty rotten quality in my book. Spend the $$ and get a good cartridge type. Will have to have the casing for each cal. but they at least work.. At least I got my money back.. FYI Natchez and Cheaper than Dirt..

I like the cartridge style in the chamber by AimShot

Have tried the muzzle insert lazers, chamber type lazers, spud mounted (Bushnell type) scopes and the Leupold magnetic scope tool.

Still tend to bore sight those rifles where the bolts can be removed and using the Leupold device when not able to do so. Just easier and usually only requires minor adjustment at the range.

Thanks All,
I am fitting a Model 71 Lever Action Winchester (that the previous owner drilled for a scope) with a custom made scope mount and Scout type scope. (My setup will have the scope sitting right over the barrel and forward of the receiver, accomodating the top ejection that most Winny lever rifles have. Obviously removing the bolt was going to be a chore, so the laser unit seemed to be a good idea.
Using the bore insert laser that a friend offered seemed to be the right and conveninet way to align the bore and scope as part of the task of match drilling my scope mount to mate with the already drilled receiver holes.

It'll work fine. As mentioned, just don't remove it from the barrel by firing ammunition.

The cartridge-shaped ones will also work and make it impossible to accidentally shoot out, and if you are going to buy one you can consider that. The spud types are cheaper (as long as you don't do the shoot-out trick).

Leaving one in the barrel is a problem if you use them at the range. That is one reason I do not use mine where I shoot. I use my barrel mounted laser in the shop only to presight the rifle before I go to the range. I too have seen those pictures.

I tried to get by with a cheap-o fiber optic one with interchangeable chamber sized deallies. the laser was a small black plastic gismo that had this fiberoptic cable coming out of it. I tried it a few times and gave up. that thing was a pain in the you know what. I'll upgrade to a chamber shapped one some day. I also saw a cool little gizmo made by Luepold at the range Saturday.

this kid down a few lanes from me was having trouble getting on paper. somebody popped this on his gun and had him on paper and in the black on the first shot.

There is obviously something wrong with me...I hate them.

I've never had a problem eyeballing through the bore at about 25 yards or so, and tightening down the scope. One shot at paper at 50 yards, adjust the crosshairs, and then another shot at paper at 100 yards, adjust...fire your three (or five, or whatever) shot group, adjust, another group to make sure, and you're done.

Other than moving your target out, it nearly takes me as long to type it all as it does to do it.

Helix,

I can't tell from the picture how that is used? Can you describe it?


Marsms,

The lasers save you the most bother setting up a scope for a self-loader or pump or lever action. You'd need to try to work with a dental mirror or pull the lever gun lever and bolt to bore sight those.

Another method a friend of mine used to use is to take a piece of scientific graph paper with 0.1" grids. He'd mark two half inch circles on it with a magic marker an inch apart vertically. This was regardless of his actual scope height, I know, since he kept those papers pre-marked in his range gear. He'd tape the paper to a cardboard box and set it out on top of a second box at 10 yards on the 50 foot range at the club. He simply aimed at the upper circle, retrieved the paper and counted grids over from the bullet hole and up or down to the center of the lower circle, then adjusted the scope that many moa.

He'd fire a second shot to be sure he didn't have the adjustment graduations remembered wrong, and he'd make a second adjustment. I don't think I ever saw him off by more than 6" when he next took it to the 100 yard line.

I don't recall him ever bore sighting. He may have set the windage and elevation to the middle of the adjustment range when he mounted the thing at home, but maybe he didn't bother? He just didn't figure the scope adjustments were great enough to get him off an 8½"×11" paper at 10 yards. Even a fixed scope with 40 moa adjustment range could just go 2.1" either side of center at 10 yards. The main problem would be parallax, and, I suppose, some scopes won't focus that close? You'd have to live with those issues, but it will get you close.

I've never had any good luck with the laser type inserted in the muzzle of a rifle. The one I have uses O-rings to fit the rifle's bore and even at clsoe range it simply didn't seem very effective. I now have a cartridge-type that inserts into the chamber and comes on automatically when the chamber is closed. That one (.243) seems to work great and also will work for several other calibers, even more than they listed: .260, 7/08, .308, .338Fed, .358, and .356.

Magnetic boresighter

[SIZE="4"]I HAVE A "SIGHT MARK" laser boresighter that adheres to the muzzle magnetically; I haven't shot it off any of my the rifles (yet), but I believe the thing would just fly off before the barrel was harmed.
/SIZE]Works well, relatively cheap (about $40.00), and you don't poke anything into the rifling to use it.

I found the cheap ones and good one sare about the same. The one I use is a bore plug type, it goes into the barrel. If I leave it in the barrel and go to the range, it means the second coming is upon us. I have safety rules that I don't break. It's like do you ever turn your microwave oven on with nothing in it? Just some basic common sense rules are all you need.

I know there are some really super duper lazer sighters out there, but I am not sure how good those are compared to how good my shooting is. So far the one I have works well for me, it was on sale for $29.95.

Scopes, Bore Sighters, Laser Boresighter, By Bushnell at Sportsman's Guide

Wish I found this post sooner. I bought a Bushnell from SG in July 2011 and was pretty excited. I took a client to my club this weekend and we were going to watch the Tennessee State F class 1000 yard competition and sight in 2 rifles. A couple days before the event I used my fancy boresighter and dialed in my scopes. The day before the event I had nothing to do and went ahead re-boresighted just to play. Well, I was devastated to see that it wasn't even close! I tinkered around for an hour trying to eliminate error and needless to say, at the range with my client, I was not on paper at 50 yards (closest target) with either rifle. I tried to put the laser back in and I could not even see the dot on the target at 50 yards, let alone 10 yards away...... I was able to bore sight the bolt action by removing the bolt but the lever action I had to pin up a 4 ft by 4 ft piece of paper to sight it in.

Now I have a $30 cat toy.

I've had excellent results with Cabelas "in bore laser", I'm on my 2nd one, the first finally went bad, (12 yrs), if I just bore sight in my basement I'll be within 3-5 MOA, if I boresight outside at 90 ft. I'll be within 1 or 2 MOA.

Boresighter

Do yourself a favor with ANY type of laser boresighter, and chuck it up in a drill press, turn the laser on, and rotate the chuck by hand. Mine (Laserlyte plug type) would make a 6" circle at about a 24" distance! I used a cordless drill in my vise to shine it on the wall about 50' away, and adjusted the laser with an allen wrench until it stayed centered while spinning. It took about 10 minutes to do and was well worth the effort!

I'll see if Bushnell can be adjusted. Sucks to have to sight in your laser sighter!
