Checking gun stores around Gettysburg, PA I have been told by a majority of gun stores that using in-chamber cartridges with lasers for bore sighting is a worthless gesture. They sight unreliability factors such as poor machining, canted bullets, weakening batteries and etc. as reasons.

what do you think?
 
I have used them. They might or might not get you on paper at 50 yards. Sometimes they are close at 25 or so yards , sometimes not. They sometimes help with a gun that you can't bore sight. Bore sighting is much better.
 
LoL….When initially scanning the title of this thread I thought it read “66% of gun stores I visited say their optics help are absolutely worthless”.

I bore sight with a Bushnell kit that uses caliber specific arbors. Gets me on paper and saves a few rounds. No batteries to replace is a plus.
 
The only one that I ever found reliable to a limited degree was a Sitemark 9mm. Sitemark machine them v eru accurately. I use it to check sight alignment before the first trip to the range with the gun in a vise. It was relatively on. Mostly I used to periodically check my laser sight alignment periodically between range trips. I stopped using laser sights and sold the bore sight

I can bore sight a bolt gun the old fashioned way and have it on a 8x11 piece of paper at 100 yards first shot, never seen the need for them.
 
I have a few. There was a short time where I was burning off gift cards from work and whatever site I was using would do free shipping over $50. I bought reloading dies and bullets usually, but they had a no name laser sight from China in a few different calibers at like 5 bucks each so I bought them to get over the free shipping mark a few times. I saw the 223 one recently.
 
I have a laser trainer that has both 45acp and 9mm laser cartridges. Every time I use it I have to "sight it in". I.E. I have to keep rotating and reseating the laser cartridge until the laser beam lines up with my sight. For that reason I don't trust them. I have a friend that uses a laser bore sighter to sight in his rifle every year and if he can't hit the target he doesn't readjust his sights. He said he is such a bad shot that he trusts the bore sighter more than his shooting. He misses a lot of deer.

I've never tried one, as I don't really see the point. I can get a rifle close enough on paper to begin the sight in process by just removing the bolt, securing the weapon from moving, sighting through the bore and adjusting the scope to the same point. No laser needed. I have talked to and heard about folks who thought that laser bore sighting got the gun close enough to hunt with. Those folks are idiots.

I agree, the cartridge style laser bore sights are next to worthless. They need to be loose enough to fit in the chamber in the first place, and as a result they have way too much wiggle room to be an accurate bore sight. Also as mentioned, those little watch batteries that power them die in no time, and are expensive. I wasted enough money on a few of these lasers to speak from experience.

For rifles, I take the bolt out and visually sight straight down the barrel.

Probably wounds a lot of deer too. A person like that has no business hunting.
 
Well to less informed bore sight sounds impressive. Never had one since a home range it's too easy to start at 20yds . Maybe at organized ranges where you can't it would help to start at 50 and fine tune from there. I have my own tire machine but I won't knock those that don't. TGIF

Me too. Just pull the bolt get it firmly set on a set of bags and center the bore on a nice size target at 50 or 100. I can get it on a 15x25 paper target at 100 and then measure and move from there.
 
With rifles and other firearms you cant look down the bore i suppose they could be marginally beneficial.....dont know tho never used one.
 
I agree. A gun and a scope doesn't come with a brain as part of the purchase.
Off on the side a little since you brought it up - I was in a gun store on a Sunday night before deer season in PA (when hunting started on a Monday) and I actually heard a patron say, "I'll take this one (a rifle) and can you bore sight it for me. I am going out tomorrow."

This is how I do it, but I’m not nearly as accurate. I boresight by looking down the barrel while gun is in a vice pointed at the garage door. I start my actual shooting at 25 yards and a poster size sheet of paper with two dots for POA and POI. I get zeroed on paper at 25 yards first and then go out to wherever I want to confirm zero at.
 
Cats would probably still chase the dots around...


I'm not really a fan of bore sighters either and they beat in chamber laser beams. I suppose no one has ever destroyed a rifle with one like the end of bore versions...

Some would say good whisky is a waste of money, so opinions don't really matter if you get what you want out of a product.

I sight in like this and leave the toys for others to play with.


I do use lasers to swap optics though. This little adapter lets me clamp to the barrel (without messing up the finish) and adjust it to the scopes zero, then I can swap optics and put the new one right where the old one was.

Rifles I swap optics on often, like for day/night use I keep pistol lasers on them to confirm zeros without shooting.

I feel the same way. Save your money and put it towards ammo. ;)

And for those guns you cant pull the bolt and look down the bore, there's always usually a way. :)

25 yards, target dot on big box, gun firmly on sand bags on the bench, I fire a group to establish point of impact.

I immobilize the gun with the sights on center of bull (point of aim) and adjust sights til point of aim is over point of impact. This target I fired a 2nd group to confirm zero.

If I had a laser boresight cartridge, odds are I wouldn't be able find it when I needed it.
And I would still have to shoot a group or two to confirm zero or readjust zero.
