the 193grain flat softpoint have a long and interessting history, it starts with Teschner-Collath in Frankfurt/ Oder around 1900. Remember that nitro powder and jacket bullets are brandnew than and allmost every hunting gun also when new was a blackpowder gun.
Teschner Collath develop the so called Tesco Bullet, a nickel platted copper jacket softpoint in every diameter from 6,5 to 500 BP. The Tesco bullet have a very short groove diameter part, looking more than 2 driving bands. This and the soft nickel platted copper hold pressure down in old blackpowder guns with smokless powder and be very friendly in old barrels designed for blackpowder and lead bullets.
If you start to reload this cartridge stay with the tesco bullet till you have more experience with the gun. It was allways satisfy, of course there are some people in Germany making test with new solids or other bullets from time to time.
Finish powder firm Vihtavuori makes a new powder and it was possible to get more speed with the bullet now and stay in the service pressure. the CIP pressure was set to be safe in any old blackpowder gun.
Rws has drop the 9,3x72R arround 1995 because some idiots are thinking it was allmost dead.
Some times later Sellier&Bellot start produktion again, allmost copy the RWS load that havn't change realy since WW1.
The 9,3x72R have a .364 dia bullet, do not use .366 dia. bullet, never.
Only the 9mm Makarov pistol cartridge have the same diameter. the CIP list allow a .376 dia. bullet, please do not confuse about this . It means only lead bullets or bullets like the Tesco having 2 or more driving bands and only the upper driving band have the ,376 dia. It is not realy possible to load such a bullet in the case , only the "stopring" over the case mouth can have it and will chamber.
There are secrets and problems with this cartridge and you have to look at the old blackpowder round to understand it
Than RWS comes back with the cartridge, believe in 2004.
So its living more than before.
