According to an old ballistics principle cartridges can not hit targets which are farther than 40 - 50 m as the shot pattern dissipates so much to become useless! But with our new system we have revolutionised ballistics as we can produce two shot patterns in sequence. In fact, the head patch creates an air pocket than takes the pellets expelled by the first patch with it ( photos 1 and 2 part A ). These pellets are then followed by the intermediate and final ones ( photos 1 and 2 parts B and C ) so that a long and narrow train of pellets ( photos 3 and 4 ) is produced. At 10 m the shot-pattern diameter does not exceed 2-3 cm as the air pocket caused by the first head patch takes the pellets with it and makes it possible to keep a high speed even at long distances ( 70 - 80 m ). Therefore you can hit targets which are 2 or 3 times farther away than targets hit with traditional cartridges !!! Caliber 12-70 NO MAGNUM
