Cartridge 9x72R
      #353431 - 15/05/21 10:55 PM

Who knows the cartridge 9x72R or under the name 8,8x72R ?

It is not about the cartridges 400/360 Nitro Express, 9x70mm Mauser or 9,3x72R.

It is not either the cartridge 9x71R Peterlongo.

The cartridge 9x72R seems like a cartridge in itself.

I don’t know any cartridge named “9x72R”, but there may be a common confusion about the old German proofmarks. From 1911 to 1939 German proofhouses marked neither he bullet nor the groove diameter nor the cartridge name with their marks, but the bore/land diameter of the barrel. This was measured by pushing cylindrical gages in .1 mm increments through the barrel. If an 8.8 mm cylinder passed, but an 8.9 mm one did not, the barrel was marked 8.8 mm. So you have to add two times the groove depth to that land diameter to get at the bullet diameter. “8.8 mm / 72” is a common marking found on 9.3 x 72R barrels with the deep bp-lead bullet grooves. As the 8.8 mm mark is found on smokeless 9mm barrels too, misinterpreting such a mark may have lead to the “invention” of a non-existing “9x72R” cartridge. Remember, min-max rifle bore-groove dimensions were fixed in 1926 only. Before, many undersized (by later standards) barrels were proofed if they stood firing he proof load.

That's right, it could be that it is just a wrong name for the cartridge 9,3x72R.

Thank you for the information.

Many 9.3x72r have "tight" bores. My kipplauf shoots a 0.359" (9.1mm) bullet. I initially tried shooting a 9.3 mm bullet and it would not chamber. Talking to others with 9.3x72r rifles, I was advised that some shoot bullets as small as 0.354" which would make that rifle a 9x72R.

It's about an old drilling, unfortunately there are no pictures.

The 9.3x72R, normalised in 1909, was THE drilling cartridge after 1911. A drilling in any other "about 9 mm x 72R" chambering would be a white elephant.

The 9x70 Förster is identical to the .400/350 Rigby
