You have to "read" what each one stands for, as there no rymn or reasonfor the names of many of them. (nothing you can relate to that is) You just have to get a book like was said and read about each one.

For instance, the 30/30 stands for a 30 cal bullet with 30 grains of black powder behind it! No, no one uses blk powder today in a 30/30. The 308 Win. stands for .308 being the bullet diameter in inches, and Win. is Winchesterwho put it on the market as a standard round.

And on it goes.............
