with a serial number over 20000 in 1912-1914 it fits excellent in my own theory that Teschner Collath had the most productive time between 1894 and 1914. this were very optimistic twenty years of the biggest boom the world have seen till then. something that is forgotten because of the great war now.

to bad its not a 6,5x70R anymore, I like the pencil cartridge because its a little bit strange. the 7x72R was not realy a big improvement or is it possible to load this cartridge legal for big game under the german hunting law?
its allways astonishing how many Tesco Drillings you see, probably more than guns. it could not be only guns were scrapped so they must have made a lot of Drillings before the war

think I will stay with paper shells, 400 are more than enough and I have more once fired paper and plastic shells on stock. to be honest I have used plastic shells with BP in the past also for old guns.
its true that I hate this stuff but with truck loads on my clay target range its hard to resist.
