Here are a few 7.62x25mm Tokarev cartridges that I recently sectioned.
Left to Right:
Czech Blank (bxn 59) suitable for use in 9x19mm and 7.62x25mm weapons? Note the single flash hole and smaller diameter primer.
Soviet brass cased Blank (38 73).
Soviet steel core Ball (38 ??) Post-WWII.
Soviet lead core ball with steel case (38 “A”) note how far into the projectile the “dot” type case mouth crimp goes.
Soviet lead core ball with brass case (38 44).
The one detail I add to my sectioned cartridges that I do not think anyone else does is to insert an inert substitute for the primer composition. I think this adds a lot to the finished product. I’m still working on a way to replicate the paper or foil seal over the mix and to color the mixes to replicate the originals. Some are grey, some are brown, some are bright yellow.
