RE: whats the difference between the 30.06 an 30.06 spring field
Yes they are the same thing.
The 30-06 was originally called the 30-03 (30 caliber and developed in 1903). In 1906 the Army decided to shorten the neck and shoulder to what it is today hence 30-06 (30 caliber and developed in 1906). The Springfield designation comes from the cartridge being originally developed out of the Springfield armory.
