Ok you asked for it so here goes. I am a cartridge collector and specialise in this caliber. There is a large hard cover book in publication strickly about the 30-06 caliber. As everyone knows the "30" stands for 30 caliber and "06" stands for the year it went into service 1906. HOWEVER the inventors have the right to name the cartridge and its original name is " BALL CARTRIDGE CALIBER 30 MODEL 1906". When sporting ammunition was loaded for it ,Winchester called their ammo "30 government 1906" and labeled their rifle barrels "30 GOVT 06". Remington called their ammo "30 SPRINGFIELD 1906" and labeled their barrels the same. I t wasnt until 1934, 28 years after its introduction that the first cartridge headstamp actually said 30-06. And another interesting tidbit, there is over 10,000 different varities of 30-06's. By the way does anyone have any interesting single or boxed ammo they are willing to barter away????????
