Cold sighting laser cartridge Sightmark cal.12. Question about cold sighting laser cartridges 12 gauge sighting cartridge

PHP SightMark SM39007 is used for cold zeroing of 12-gauge smoothbore shotguns. Laser SightMark cartridge SM39007 allows you to zero or check previously zeroed hunting weapons without firing real cartridges, and can be used for zeroing optical and collimator sights, night vision sights, laser designators, luminous front sights and rear sights. The ability to use a cartridge for zeroing a specific weapon absolutely does not depend on its type or brand and is tied only to the caliber of the weapon.
The total length of the SightMark SM39007 cartridge is 60 millimeters, which allows you to zero the vast majority of smoothbore weapons 12 gauge, including the most popular, with a chamber chambered for 12x65, 12x70, 12x76 and 12x89 millimeters - IZH-27, TOZ-34, MR-153, MC 21-12, Saiga-12, Bekas, Vepr-12, Remington, Winchester, Mossberg, Browning, Benelli, Fabarm, Beretta and many others.

The total length of the cartridge is 60 mm.
The weight of the cartridge is no more than 40 grams.

Using the SightMark SM39007 12 gauge laser cartridge for initial cold zeroing of weapons.
Unscrew the bottom of the laser cartridge sleeve. Insert the batteries, observing the correct polarity, into the laser socket and screw the bottom clockwise without much effort. The laser beam will burn continuously.
1. Place the SightMark SM39007 12 Gauge Cold Shot Laser Cartridge into the weapon's chamber and the laser beam will shine through the bore and create an image of a red dot on any surface.
2. Select a flat, vertical surface within the intended shooting range and aim the laser beam at it.
3. The weapon is zeroed by aligning the aiming line with the axis of the barrel at a given distance. The position of the center of the light spot corresponds to the weapon's midpoint of impact (MIP), without taking into account the ballistics of the bullet's flight path.
Using the handwheels for entering vertical and horizontal adjustments of the sight, align the aiming mark with the red dot of the laser cartridge for cold zeroing. In a small room, cold sighting can be performed at a shorter distance. In this case, the laser point must be below the aiming point at a distance determined by the ballistic characteristics of the ammunition used.
4. The result of cold zeroing must be checked “hot”, using high-quality bullet ammunition. If necessary, make adjustments. Perform test firing with shot cartridges.

Using the SightMark SM39007 12 gauge cartridge to monitor the condition of a weapon that has already been hot-sighted.
We assume that the weapon was shot at the required distance “hot”, that is, with real ammunition, after the initial cold shooting of the weapon.
1. Place a laser cartridge in the chamber of the weapon, and the laser beam, shining through the bore, will form an image of a red dot on any surface.
2. Select a flat vertical surface at a distance of about 15-25 meters from you and place the sighting target from the cartridge kit on it. Point the laser beam at the target.
3. Align the reticle of the scope with the center of the sighting target. While observing the red dot on the surface of the sighting target through the scope, remember its position relative to the crosshair of the aiming mark. For your sight-weapon-cartridge complex, the position of the laser dot and crosshair is a constant.
4. In the future, wherever you are - at the shooting range, at the shooting range or on the hunt, you will be able, using a laser cartridge and a sighting target, to find out whether the position of your sight on the weapon has been preserved, as well as the result of entering corrections during the “hot” shooting after transportation or not. If necessary, use the means of adjusting the sight to ensure that the position of the crosshairs of the aiming mark corresponds to the red dot. In this case, the verification procedure must be carried out at the same distance as the actions in point 3.

Using the SightMark SM39007 12 Gauge Laser Chuck for training.
Activate the laser cartridge and aim at a target located at your intended shooting range. Try to hold the weapon as stable as possible. You will be able to evaluate how the barrel “walks” based on the movement of the laser dot and take measures to hold the weapon more stable.
Another exercise is performed with the help of an assistant, who must block the laser beam at the exit from the barrel bore with some opaque object. Aim at the target and ask your assistant to release the barrel. You will see where the bullet will actually go.

Photo 1. Sales package:
laser cartridge - 1 pc., battery LR44 (AG13) - 3 pcs., case for storage and transportation - 1 pc.
Packaging - blister.

Laser cartridge SightMark is an independent, ready-to-use product.
Allows you to zero or check the zeroing of hunting weapons without firing cartridges.
This is especially true when using expensive ammunition.
You can fine-tune any sighting devices of your weapon during the “cold” zeroing stage.
It is impossible not to note another useful function of these laser sighting cartridges - the ability, right before a hunt, to very quickly check whether your well-aimed optical sight has gone astray during transportation. Remember that misses are not uncommon for this reason.
The light weight and shape of the cartridge are convenient to use and do not take up much space in the equipment of the shooter and hunter.

Specifications:

Laser type: red semiconductor ( Visible Red Laser).
Laser wavelength 632- 650 nm.
Emitter power less than 5 mW.
Operating modes ON / OFF (On / Off end cap).
Shooting distance from 15 m to 180 m. The maximum distance depends on lighting conditions.
The optimal shooting distance from 15 m up to 100 m.
Spot size at a distance 100 m approximately 50 mm (approx. 2").
The non-parallelism of the laser beam to the barrel axis is 0.0005 radians.
Power supply: 2 batteries LR48/AG5 1.5V or 3 batteries LR41/AG3 1.5V ( 1 hour continuous operation).
Chuck body material brass.
Weight about 100 g.
Operating temperature range from -10 to +50 deg C.

Application of laser cartridge:

The system is absolutely independent of the type of weapon and is “tied” only to the caliber.
Standard shooting distance 25 meters. Place a target at this distance for shooting. Target dimensions: 140 mm x 140 mm. The target division value is 25 mm.

If necessary, secure the weapon in a sighting vise, place it on a bipod, or place it on a resting surface.
Unscrew the bottom of the Laser Bore Sights counterclockwise.

Paste into plastic container batteries, observing polarity.

Insert the red plastic container (insulator) into the laser module (cartridge) and screw the bottom clockwise without much effort. The laser beam will burn continuously.

Attention: Be careful when using the laser cartridge to avoid damaging your eyes.
Attention: It is forbidden to look towards the beam, direct radiation into a person’s eye, or place foreign objects in the path of the laser beam that cause its mirror reflection.
Attention: When installing batteries, observe the correct polarity.
Insert the powered laser model into the chamber of a rifle or shotgun of the appropriate caliber (on bolt-action carbines, the bolt must be closed).
Align the laser dot of the sighting cartridge with the center of the target. When zeroing at a distance of 25 meters, the aiming mark of the optical sight is aligned with the laser dot projected at the center of the target.
The weapon is zeroed by aligning the aiming line with the axis of the barrel at a given distance. The position of the center of the light spot corresponds to the weapon's midpoint of impact (MIP), without taking into account the ballistics of the bullet's flight path.
Align the aiming line of the open sighting device of the weapon or those mounted on it sighting devices: optical, collimator sights, laser target designators, luminous front sights and rear sights with the center of the light spot of the laser cartridge.
When the laser beam deviates from the center of the target by 30 or 50 mm or another higher value Using the windage and elevation adjustment dials on your scope, begin to adjust the reticle of your scope to the correct position. This is done by clicking on your crosshair.
Zeroing is considered complete if the crosshair of the weapon's sighting device is aligned with the center of the laser emitter spot aimed at the object.
Note: If, in the process of adjusting the sighting devices, you aim at the center of the laser dot, then the bullet will hit the same spot only at those distances where the trajectory decrease is 0, for example 100 m. Therefore, if you plan to use the weapon at a greater or shorter distance, it is necessary to take into account the change trajectories in accordance with ballistic tables for a given ammunition.
Remove the laser cartridge from the chamber. By turning the bottom of the sleeve counterclockwise, turn off the laser, or remove the batteries from the Laser Bore Sights.

Instructions for use and storage:

Attention: Remove the batteries from the cartridge when not in use for a long period of time. Deteriorated batteries can destroy the device.
The device requires careful and careful handling.
According to the degree of radiation hazard, the device belongs to class 2 CH 5804-91.
The laser sighting module must be stored in a clean room at a temperature from +5 to + 40 degrees C and relative humidity air no more than 60%. (At air temperatures below +25 degrees C, an increase in relative humidity to 80% is allowed.)

Greetings, dear community!
I would like to buy myself such a laser cartridge. Maybe someone has already used these cartridges. I am interested in the efficiency and beam range. Please respond and leave a review.

Zmeygo Rynych 03-04-2016 12:01

Wasted money.

Frayman 03-04-2016 12:04

I have one.
When installing the target, you can roughly nail it in order to at least hit the target. But it is advisable to do this at night.

kyk 03-04-2016 12:32

Bullshit, better ammo buy

River 03-04-2016 19:04

There are expensive ones and there are cheap ones. The cheap ones usually don't work very well. They don't even get into the chamber. The same effect can be achieved by placing a piece of mirror on plasticine. A good PLP is expensive.
Decide, try. Then tell me.

Frayman 03-04-2016 19:51

I bought a cheap one from Aliexpress. Put it on new rifle new sight. I inserted the cartridge, shone it at night at the neighboring house, and nailed the sight to the spot. At the shooting range I immediately started hitting the shield. The laser cartridge was no longer available. I think he saved me a dozen rounds.

Vladimir 150RUS 03-04-2016 20:10

Bullshit, it's better to buy cartridges

No, it’s far from bullshit, that’s the truth -

In addition, it really helps to control the sight, it shows, of course, not exactly the STP, but somewhere around, I have one on the Tiger and have been using it for a long time, at 50 meters there is a 5-7 cm difference from the STP, a lost sight can be easily checked if you approach it wisely - zeroed you point the sight at the object, remember the difference in readings, everything else is used to check the sight. It generally makes life easier for night light owners and saves hundreds of rounds of ammunition.
The thing is, in a word, necessary, don’t listen to those who say bullshit, or those who say that they set up a point and shot a nickel. These are those who didn’t hold it in their hands but have an opinion.

Zmeygo Rynych 03-04-2016 20:52

And some specialists shoot (!) with a laser cartridge (!) at 200m (!) and then go on a responsible (!) expensive hunt (!) and miss (?) and wonder WHY (!!!) damn (!)

The laser cartridge is a brilliant solution to a non-existent problem and a scam of suckers.

chijevs 03-04-2016 21:01

the cartridge is nonsense - a multi-caliber set is better - if not bent

I also use an inexpensive one, I change attachments on carbines - a sight, a callimator, covers, crowns, for rough alignment of the first shot it will work fine, and without noise and dust

karakurt 03-04-2016 21:15

This cartridge is needed on semi-automatic weapons and weapons where it is not possible to make a rough alignment of the optics along the bore. The alignment needs to be done at 25-30 meters, because this corresponds to a near zero. You should not expect high accuracy, because when the device is rotated, the point describes a circle/ellipse on the target, but as they correctly said, it will help save time and ammunition when zeroing in sight cartridges. You are already guaranteed to hit the target and will know where and how much to turn the adjustment drums.
The second device is more universal in caliber, but there are cases when it cannot be inserted into the barrel without distortion and the first one will be preferable.

hunter143 03-04-2016 21:27

Thanks for the feedback. I think the cartridge in the top photo will be more accurate.

disz 03-04-2016 21:29

quote: You shouldn't expect high accuracy, because... when the device is rotated, the point describes a circle/ellipse on the target,

But you don’t really need to twist the cartridge. It must always be inserted into the chamber with one side up (bottom, side). Mark the side and one side up.
Further..., it is convenient when changing OP. You can roughly “shoot” even at home: hang an A4 sheet on the wall, draw a dot in the place of the LP bunny and the OP mark (crosshair) point. You rearrange the OP and compare these labels. Also saves money and time.
The thing is useful. I have both 7.62x39 and 22LR.

kyk 04-04-2016 12:41

Damn, guys, the chores are full of crap. The cartridge and other laser crap have nothing to do with STP. How often do you rearrange your sights? I have no problems, the night light/day light has a normal error for hunting, but I still have to burn one or three cartridges for my own peace of mind.

Vladimir 150RUS 04-04-2016 12:56

I don’t think that any accuracy of more than 5 cm is possible on a device of any price, and the problem is not in the laser cartridge itself, but in the fact that at least this cartridge is not blown across your chamber, plus the misalignment of the laser and the laser.

quote: Originally posted by disz:

Rough zeroing saves already expensive cartridges. The task of the LP is to catch on to the target, and then you accurately shoot at the target.

Absolutely right, this thing is needed, just not to use it in the same way as they wrote above about 200 meters and responsible hunts.

In the quotation book!!! Think about what you wrote.

quote: Originally posted by kyk:

And it’s easier to make adjustments to the sight using the minute grid on the target - it will be more accurate than using a laser.
It is possible to roughly draw the sight onto A4 sheet without a laser.

And you can also go to the toilet in the pit on the street, count in columns without using a calculator, call on your home phone, well, why do we really need the benefits of civilization............. Why make it easier for yourself life then??? Everything needs to be done the old fashioned way, along the bore, to burn cartridges that cost comparable to 1 LP, well, what’s the point of all this, really... All that’s left is to stop using the roads, it’ll be a shorter route through the forest...

And its further installation is not the most difficult thing. It is extremely necessary to ensure the alignment of the axis of the barrel bore and the optical axis of the sight itself; in other words, it is necessary to make sure that both the barrel and the sight “look” at the same point on the target.

Where the sight is pointing is understandable, and the position of the aiming point itself can usually be adjusted with verniers on the sight itself, but at what point is the barrel pointed? This question cannot be answered so easily. Really, where? The answer will be given by a series of shots from a rigidly mounted weapon. But this is not a panacea, since the quality of the shots greatly depends on the quality of the ammunition itself. Even if the cartridges are from the same box and the gun is fixed motionless on the machine, the bullets will by no means hit the same point on the target. Leave the fantasy of 100% hits to the Robin Hood films. Only he could use an arrow to split his previous arrow that hit the target. In life, everything is completely different. Please note that I am talking about the usual "mass" firearms, not about special ones sniper complexes, made individually, with micro-tolerances and for special ammunition!

In a word, when shooting a gun under a new sight, you will spend more than one box of ammunition hitting the target... and your pocket too. Needless to say, dismantling/installing the sight will most likely require re-shooting?

Large financial and time costs can be avoided by purchasing the device that is discussed below.
So, welcome!!! - Laser cartridge of cold zeroing!

The principle of operation is as simple as a moo - by placing an engaged cartridge in the chamber, you see at which point on the target the axis of the barrel bore is directed. All that remains is to align the aiming point of your optics with the point from the laser beam emitted by the cold-shooting cartridge. All! No shots required. Work for a couple of minutes and 0 financial costs Once you buy such a cartridge of the required caliber and then use it for the rest of your life, buying batteries every 10 years

So, I bought the lot on eBay from the seller hossen-usa from China.
The cost of the lot is $13.88 with trackless free shipping.
I paid with Palka on 01/11/2012, the parcel arrived on 02/7/2012. Almost a month. Quickly... h34r:

And now for some funny pictures

The parcel itself is a regular white pimply envelope:

Inside is a small package:

Delivery set: cold sighting cartridge, three LR44 coin-cell batteries and instructions in English.

The cartridge itself has the usual silhouette for a smoothbore cartridge. The caliber and polarity of the batteries are indicated on the side. The paintwork of the case is durable - it was not scratched on the walls of the chamber.

There is a recess with a laser on top:

The bottom of the cartridge is the battery compartment cover:

There is no power button on the cartridge body. This is logical, since the walls of the cartridge must fit tightly to the walls of the chamber. There is simply no room left for the button. The cartridge is turned off by partially unscrewing the bottom.

The cartridge sits tightly in the chamber, without play. This is important!
