Introduced in 1901, the 600 Nitro was never widely used but it remained the pinnacle of African cartridges for many years. A 900 gr bullet at between 1850 – 2050 fps meant that it had ample power for any game. The headstamp on these cases although not Bertram were made in the Bertram factory to the same standards as his other brass. The price is for 20 cases and the shipping weight is 750 g.
