- The cartridge primer must be secured in its pocket by a crimping process. The German made WW2 7.92X57 cartridges have the primer secured in place by 3 very small dots which actually look like tiny squares or rectangles. Some 7.62X25 Tokarev cartridges have the bullet crimped in the cartridge case by 3 small dots. Some primer screws used for larger caliber shell cases are also secured in place only by one dot punch which prevents the primer to get unscrewed. — QUESTION: Would it be correct to call “dot crimp style” the method of primer [or bullet] crimping which uses the dots??? Thanks in advance for any help, Liviu 02/23/07
I think the term “Stab Crimp” is more commonly used, at least in the US.
