The use of one pellet or another, with one shape or another and with one weight or another will provide variations in the speed of the projectile. With the chronograph, we can find the pellet that most closely approximates the ideal speed for the caliber we are using for the sake of maximum precision or for any other purpose. We can say that the chronograph is a magnificent tool that provides us with information that we cannot obtain in any other way, without it we are blind, that is the matter. The R2A chrono is supplied with 2 AA batteries and it is possible to connect the R2A chrono with a external power adapter (optional). Alsocan it be connected to your PC with a USB to RS232 cable (not included) There are many functions in the LMBR chronograph that help us in our work to know what we have to do to reach our goals with a certain weapon or ammunition, the device calculates Averages, Deviations, Variances, etc. of a sampling, that is, a series of statistical data that helps us to know in depth the characteristics of a weapon and its ammunition by reading the effects provided by the chronograph. A well-used LMBR chronograph is a must-have for all shooting and hunting enthusiasts. Shoot through the chronograph window with a distance from the muzzle (for airguns) of about 10/20 cm. and about 40/50 cm in the case of a 22 LR caliber firearm. or similar. The apparatus will give the projectile velocity and energy readings in joules directly. Suitable for air rifles, air pistols, firearms (not Shotguns) and archery. System units: Metric and imperial (Latest 2018 software version).

If when making a series of shots with an airgun the readings are irregular with large jumps in the speed of the projectile, we already have a major problem because the rifle will not group correctly. Different speeds of the projectile, very different, will cause defects in the grouping of the impacts, this denotes a malfunction of the valve / regulator in a PCP rifle or in the spring and compression system of a piston rifle or any other failure related to this and that can occur in pneumatic rifles (friction, dragging, pieces or broken tires etc.) in any case a defect or fault that must be found and fixed so that the constancy of the shots is adequate again.

I HAVE THE POWER

However, if I put the JSBs through the wrong gun, this will drop to 590fps. There is no doubt that a faster pellet will take less wind and have a flatter trajectory, and there can also be a bigger difference between pellets with different head sizes. Obtain directly in joules (or in ft / lb - Imperial System) the energy of the projectiles of your pneumatic weapon or firearm (Cal .22 LR or similar), you just have to provide the weight of the projectile to the device, recording it in it by operating the buttons that appear on the front of it. Shoot through the window, the device will inform you of the speed of the projectile and the energy calculated directly in joules or in ft / lb depending on whether we choose the metric system or the imperial system. If you take testing your air rifles seriously, you’ll really want to take a look at this chrono which is the last in our list of chronographs for airguns. According to Skan, police forces use a version of the product here to test potentially errant air rifles and pistols. Many airgun manufacturers are customers too.

The MagnetoSpeed Sporter chronograph kit is designed for use on barrels from 1/2 inch up to 1 inch in diameter and can accommodate muzzle brakes and flash hiders up to 2.7 inches in length. It is ideal for contoured rifle barrels (sporter barrels). By shooting trough the LMBR R2A chronographthe display shows you the exact pellet speed and power of the rifle. The simple and decent design makes the chronovery easy to use. When the cover is replaced, be careful that the two slots allow access to the sensors below. It is possible to fit it the wrong way round, which means the sensors are occluded and the device becomes inoperative. The other advantage with the R2A is that you can set it up so that it sits just in front of your muzzle, and depending on how high your scope is, you can shoot your targets and just look up at the display and see your velocity. This way, if you have a shot that hits high or low, you can see if there has been a power fluctuation at the muzzle. The R2A will remember a 250 string of pellets and there is no doubt that this chronograph will help you to be more consistent and so choose the best pellet for your rifle. Knowing the speed of the projectiles is useful for many things but mainly, in the subject that concerns us, to obtain ballistic information of the projectiles fired.

Su polivalencia resulta exquisita. Las pruebas se realizaron con armas cortas y largas de aire, así como cortas y largas también de fuego, aprovechando situaciones extremas para comprobar la capacidad del equipo. Registró perfectamente desde las lecturas más pobres de un arma corta de aire (129m/s), pasando por carabinas PCP de alta potencia, pistolas de 9mm, hasta fusiles con munición casi trisónica, como son la familia 22 de fuego central que trabajan por encima de los 1000m/s), no obstante según el fabricante puede medir hasta 2000m/s. The big advantage of a chrono’ like the LMBR R2a is the ability to place it downrange. The large 120mm aperture means that you can shoot it safely from a distance, and unless you are having a very bad day, you can shoot it safely.

El equipo admite previamente ajustes para entregar su máxima precisión, calibración de lectores, así como para indicarle si vamos a usar armas de aire o de fuego. No obstante he de señalar que con el ajuste de fuego, el crono realizó también las mediciones con aire a la perfección. Sus lectores más anchos que los habituales en los equipos ópticos actuales, nos permiten la suficiente imperfección en los ángulos de disparo para que la lectura sea correcta. De hecho se puenteó con un CHRONY y mientras éste daba sus típicos errores de lectura si la luz del cielo cambiaba o el transito del proyectil no era bastante alineado, el nuevo equipo no dio UN SOLO ERROR DE LECTURA durante la semana que se sometió a pruebas intensivas. The unit comes with a lead to transfer information via a data port to a computer, and a charging cable which also attaches to a PC. The Shooting Party recommends the Ballistically Brilliant Chronograph be fully charged before use, and says it can handle velocities up to 2,789 fps.Chronograph readings can be very useful in diagnosing faults, particularly when there are instances of inconsistent velocities causing inaccuracies down-range. I hope I’ve given a few good reasons for you to rush out and buy one, which of course, leads to the question of choice because the market is awash with models of various prices.I already have a couple of chronographs that I use regularly – a Skan, and an FX Radar, which are excellent and come highly recommended, although they both have one limitation. Both are difficult to use down-range, particularly if you don’t want to damage them. If recording terminal energy is your bag, like our own Gary Wain, then you need a chronograph, which with care can be used down-range. So, if this is you, and you also want a chronograph that can be used in the workshop, then the LMBR R2A could be your new best friend. FROM POLAND TO YORKSHIRE The constancy in the speed of the projectiles does not imply perfect precision, at all, but we can say that it is the first and fundamental step for a weapon to be accurate.
