In how many steps you can delimit a prey?
We can say that up to 30 meters and with properly selected diameter shot and choke barrel we can almost certainly result if of course we intend correctly. Throws over 30 meters may also be effective but raise math fewer chances of success. As the distance is reduced and the number of shot they can find prey, and the kinetic energy is directly related to the effectiveness of prosvolis of prey.
Loud cartridge = good?
The recoil of the cartridge is not in any way a qualitative characteristic. What really is important is the combination of the right speed and pressure, which is achieved with the right combination of materials. The experience and knowledge of the manufacturer, coupled with the appropriate instruments ballistic control are prerequisites for making a correct cartridge.
Developed pressure and kick
The kicking of the cartridge depends on many factors. There are cartridges with a low kick and dangerous pressures, as can be cartridges forcefully kick and absolutely intolerable pressures. What should be noted is that the increased kick a cartridge does not imply, as many believe, increased pressure, simply because the main factor causing increased sense kicking in a cartridge are the initial velocities of the beam shot pattern, combined with the weight of charge in shot and not developing maximum pressures.
What diameter (NP) using
Usually each prey can hunted with at least 2-3 different alternatives to the diameter of the shot, according to the location and way of hunting. However remember that the fine shot "open" sooner, but lose faster the kinetic energy as the distance. Consequently, hunting in nearby destinations have advantage using psilotera shot while on longer distances have the advantage of larger diameter shot.
High speeds and preaim
Duck flies with a speed of 70 km / h, from left to right, just 30m from the hunter who has a cartridge with speed:
A) V10 = 355 m / s (NP 5)
You need pre-collimating 1.63 meters.
B) V10 = 340 m / s (NP 6)
You need pre-collimating 1.71 meters.
The differences in the pre-shooting between two cartridges with different speeds, is relatively small.
Attention . The speed is very important for the efficiency of the cartridge due to the kinetic energy acquired by the shot.
Set the speed of buckshot
V1 = speed at 1 meter from the muzzle:
Usually ranges from 390 to 460 m / Mon for vp 1-10
V2, 5 = speed of 2.5 meters from the muzzle:
In Regulation CIP and the minimum distance which can be measured in a cartridge. Instrumentation required, but their arrangement guaranteeing the reliability of the results.
V10 = speed at 10 meters from the muzzle:
This type of measurement is extremely reliable and comes closer to the reality of hunting shots. The speeds usually range from 305 to 375 m / Mon for nr.1-10
The kinetic energy of buckshot
The ability of lead shot in the payment of prey depends mainly of their kinetic energy. The kinetic energy, in turn, is proportional to the mass of lead shot and the initial speed of which will give the charge of the cartridge. Fraction of larger diameter than those that fit into a hunting game, make the distribution of the cartridge 'poorer' in number shot. Initial speeds higher than those needed degrades the quality of equalizing shot.
Soft and hard shot
The old thought imperative using soft shot, because they considered that very hard shot make sunlit wounds without paying prey. The theory of the through wounds disputed today, intensively and even with several thiramatika documents. Actually very hard shot (those that have content 3.5 to 5% antimony) cause somewhat less tissue destruction in prey due to reduced deformation, but clearly give better distribution in shot and slightly higher concentrations in soft shot . However most manufacturers cartridges and most hunters today prefer intermediate solution of semi shot.
Μaterials plug-in cartridges
A low quality material pluggable may allow indefinite escaping gases, and thus destroying the power of the beam shot pattern and overall quality of the shot. It is commonplace to those involved with modern ballistics that current filler are about equally, very high. At least in terms of powders, the casings and caps, manufactured solely by large corporations with intense competition. Not so with materials pluggable (plugs and concentrators) that may come from large industries or small cottage industries anonymous. The obturator, then, is that element of a charge to be checked especially its quality, because it determines the recovery or canceling the rest of the hole quality materials and combining them.
Cartridges cluster and open choke
"The more open the choke, the greater the dispersion" A cartridge dispersion perform better with an open choke. Take a test and confirm the rule yourself.
«Winter" and "summer cartridges»
From various measurements carried out with the help of suitable organs demonstrates that differences in temperature around 15-20 degrees (ie from 30 ° C to 15-10 ° C) is not substantially affected by the performance of the cartridge. In fact, the cartridges are made of first class materials can be used all the time because very little affected by changes in weather.
However, temperatures around 0 ° C, (which are found in some parts of our country for a few months) is able to affect to some extent the ballistic characteristics of the cartridge, but not to such an extent as to make it non- efficiently.
It is estimated that a cartridge will lose (depending on the type of powder) from 3 to 15% of the pressure of 0.5-3% and the speeds of from +30 ° C to 0 ° C. These differences, perhaps, felt the very limit shots.
Proper storage cartridge
Lack of moisture is necessary for the storage of ammunition us. The temperature fluctuations condense dangerous for the viability of gunpowder cartridges of us. So breathable packaging (paper or wood and not metal or plastic) and areas without intense and sharp transitions temperatures and no humidity are the ideal conditions for long-term storage of our cartridges. Accessories, such as silicates (silica) or naphthalene marbles in the closet of our cartridges are valuable safeguards for their longevity.
