Review of the new hunting cartridge spark, characteristics, advantages and disadvantages
Perhaps one of the most important and fundamental ballistic characteristics of the hunting cartridge is the speed of a bullet or Grabovogo charge. Once it becomes clear that at the highest possible speed of a bullet, in General, simplifies the task of the hunter defeat the selected target. Here it can be noted that with this increases the range of defeats the purpose. Professionals who work in the field of cartridge manufacture, always try to increase these figures in a better way and, in principle, they do it pretty well. Also not surprisingly, over these options work and experienced hunters, because to improve performance is possible without the use of complex technologies. Was carried out the improvement through the optimal varieties of gunpowder, and the increase in mass of the powder charge, for this purpose we used special methods of selection of various components for cartridge.
Do not think that you will be able to charge the maximum powder charge, as currently set known limit. Approved that the maximum pressure of powder gases in the barrel of a conventional rifle in any case may not exceed the limits in 714 kgs per centimeter square. If you decide to exceed the permitted limits, then ultimately this can lead to the damage of your weapons, but rather happens the most terrible and irreparable – the gap trunks. If you start to self-select appropriate components for the cartridge, then eventually you will be able to raise the overall flight speed, but also don’t forget that there is a certain limit, which is not able to give tangible security when shooting.
Remember that cartridge change can be internal only, but not changed in appearance. Many experts for a long time was testing different layouts, but also a new solution was found. At the moment there are brand new cartridges that greatly extend the capabilities in terms of speed charge for smoothbore weapons. New cartridges are individually named «Ekstra-M», this type of rounds received a paper sleeve, as well as new cartridges «spark-M» received a plastic shell casings. These two rounds has the maximum arranged by the manufacturers, so to make any changes here will not have to. New cartridges powder charge is divided into two sections, wherein the strip is cardboard, which has a small hole. This separation is necessary to temporarily delay the entry into action of the second part of the powder charge, which ultimately allows to increase the total mass of the charge, this does not increase the maximum pressure. To date, there are a large number of reviews, where professional hunters give their opinion on new cartridges, in fact, on analysis it was found that positive feedback was the order more than the negative.
Of course, in the new cartridges, there are drawbacks and they are that they don’t seem to be able to use for modern guns, since they are equipped with special dosers for powder. At the moment, manufacturers are working on new liners, which have different heights the metal substrate, and this enables the hunter to choose the best option of the cartridge for hunting. If you decide to choose for hunting shells with a height of 1.6 cm, then you will be able to provide a small mass of the first portion of the propellant charge, which can reach 0.8 grams.
