SLUG FOR HUNTING CARTRIDGES CAL .410/70 “MAGNUM ”Barnaul, Russia - December 16, 1999 -We are proud to introduce the new .410/70 caliber "Magnum" cartridge. The slug is formed as a cylinder that external diameter is equal to the diameter of the bore of the smooth – bore weapon caliber .410/70. The material of the bullet is antimonious lead marked Ssu2. GOST 1292- 84. The external side surface of the bullet has 11 guiding grooves slanting to the side surface at the angle of 10 degrees which enable steady flight at the distance of 50- 80 meters. Bullet weight is 63 g. The head of the bullet is 58,7% in diameter. A deepened conical cavity of bullet tail is 73,4% of its diameter. The external surface of tail ends, forming a cylindrical lug which height is 2 –2,4 % of the external diameter of the bullet.
The feature of the bullet is, the center of gravity compared with analogous bullets, is moved closer to the head. Slanting grooves at the side are properly correlated. These 2 features enable high accuracy and steady flight at maximum distance for 50 – 80 meters. Bullet dispersion at a standard distance of 35 m or 50 m is the following: 5 bullets in a circle of 6 – 8 cm at the distance of 35 m and 5 bullets in the of 12 – 14 cm at the distance of 50 m. This bullet is not intended for any larger distance.

To fix the bullet in a metal case and decrease its deform it is placed inside special plastic container which detaches on going out of the bore of a barrel. With the same purpose the container with the bullet inside is placed in a special wad- compensator of original construction.
