Magnum: What Is It Anyway?

"Magnum" is a term that perplexed many amateur shooters and gun owners. Specifically, this name is not a brand. Instead, it is a description given to high and stretched rounds. Innovation happened, and smokeless powders already superseded black particles. The latter is quite denser than black particles. Therefore, they can provide more space to their cases. The .357 magnum is one of the best examples of this setup.

Most of the guns on the past can't cater for the size of these cases. What the manufacturers did is that they lengthen the rounds of their weapons for extra safety. They called these new firearms as "magnum."

The "Magnum" label is quite hard to distinguish. Up until now, many are still arguing if a particular cartridge is a magnum or not. However, we follow an unwritten rule on this aspect. Specifically, a magnum round can exceed other cartridges when it comes to power and speed.

For instance, .30-06 rounds are considered by many as the "standard" when it comes to power. Therefore, it is quite easy to deduce that the .300 Winchester magnum is on a higher level compared to the .30-06 magnum. But still, the only difference they have is the velocity and power, not the size of the bullet.

You can say that a .35 Whelen is the magnum version of the .30-06 due to its power. But when it comes to bullet diameter, the .30-06 has a greater lead than the .35 Whelen.
