The flight speed of the shotgun shell was measured by setting the distance between the locking devices to three meters using an electronic chronograph. Thus, the average velocity of the projectile was determined at 1.5 m. The shooting was carried out in series of 10 shots in a closed shooting range at an ambient temperature of plus 10-20 ° C.
The characteristics of the weapon's combat were determined according to a generally accepted method using a standard hundred-point target when shooting at a distance of 35 meters.
Since the expected maximum pressure of powder gases developed by magnum cartridges is of the same order as the maximum pressure of domestic cartridges, an IZH-58 20-caliber rifle was used for practical shooting. The chamber in it was drilled for Canadian cartridges.
The Ego rifle was also tested in hunting conditions, on a hiking trip through the Sayan Mountains by engineers V. V. Polyakokov and A. N. Kalugin for both feathered and wild game, as well as small fur-bearing animals. The hunters were very pleased, as the IZH-58 rifle with magnum cartridges gave them almost the same capabilities as a conventional 12-caliber light rifle.
From the same rifle with a chamber for magnum cartridges, our usual cartridges with a short sleeve were fired in two series of 10 shots each. We could not detect any noticeable effect on the external ballistic characteristics of the shot. The maximum pressure of the powder gases in the bore, the magnitude of the initial velocity and the accuracy of the battle remained virtually unchanged.
The average shooting results of the two series were as follows: pressure 655 kg/cm2, speed 378 m/sec, accuracy 47.5%.
Thus, the research conducted by the authors allows us to draw the following conclusions.
Magnum type cartridges greatly expand the capabilities of a hunting rifle of the same caliber. They allow you to get (depending on the type of hunting) different sharpness of the fight and the power of the shotgun shell by changing its weight.
The use of a magnum cartridge allows a hunter to take a lighter rifle of a smaller caliber, which is especially valuable in commercial hunting, hiking, scientific expeditions, etc.
The use of such cartridges will reduce the number of calibers of manufactured rifles to two or three and thus create good conditions for mass production.
In conclusion, we believe that it is necessary to consider the possibility of producing high-capacity cartridges (such as magnum) in our factories in the near future.
