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.

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 sights on 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.

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 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.

This cartridge is used for cold sighting of twelve-gauge carbines. The brand of the weapon does not matter. If the sight of a weapon has become misaligned during transportation, or you have changed optics, and are still close to the object of hunting, you can correct the sight using a laser cartridge Red-i. It allows you to avoid firing unnecessary shots, producing unnecessary noise. With its help, shooting accuracy is ensured high quality manufacturing and precise adjustment.

Parameters of the Red-i laser cartridge, caliber 12

• The cartridge is powered by 393 batteries, which is enough to operate for up to three hours.
• The semiconductor laser beam is emitted with a power of 4 mW and a wavelength of 650 nm.
• The cartridge has a brass body with 2 o-rings.
• The cartridge turns on immediately as soon as its bottom contacts the chamber body.
• It can be turned on by pressing on the bottom of the cartridge with a metal object.
• At a distance of one hundred meters, the spot on the target will have a diameter of 2.5 cm.

Only Red-i cartridges will allow you to accurately zero your weapon at home and check your sights while hunting without firing additional shots.

Even the ejectors do not throw this cartridge out of the chamber like spent cartridges, but smoothly remove it from the chamber.The device has a special device instead of a primer, which allows you to fire blank shots without damaging the cold-zero cartridge. The cartridge is turned on automatically when it enters the chamber of the weapon.

Characteristics of the Red-i 12red laser cartridge

• Laser type: red semiconductor.
• Laser wavelength: 650 nm.
• Emitter power: 4 mW.
• Spot size at a distance of 100 m: approximately 26 mm.
• Power supply: 2 or 3 batteries type 393 (3 hours of continuous operation).
• Chuck body material: brass.

Since on smooth-bore weapons, the chamber drilling differs in diameter, on various models smooth-bore weapons, the cold laser zeroing cartridge may not fit tightly inside the chamber. The cartridge does not depend on the type of weapon and is “tied” only to the caliber.

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 the switched-on cartridge into 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 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 any play. This is important!
