Matrice Triebel 6,5 CM
The matrices appear to be very well crafted at first glance.
The manufacturer is the German company TRIEBEL.
The dies are hardened, thoroughly polished and engraved with labels.
FULL LENGTH SIZING DIE
The full-length sizing die consists of a die body and a needle, which can be replaced by an expader unit at will. The dies contain a vent hole which can be found in the shoulder area. It helps to reduce the resistance when formatting the cartridge case and to drain any excess lubricant when over-lubricating the die.
In the die you will find a .262'' diameter expander When using with Starline cartridges, I have come across the NECK TENSION 0.003''
I set the die to the so called BUMP 0.002'' (difference in length on the shoulders of the cartridge case before and after formatting 0.002''.)
