223 and 243 are two popular rifle calibers used for hunting and sport shooting. While they may seem similar, there are several differences between them, making each suitable for different purposes. In this article, we will explore the differences between these two calibers and determine which one is better for hunting.

Both 223 and 243 are centerfire cartridges, meaning the firing pin strikes the center of the cartridge case to ignite the primer. The main difference between them is their caliber, with 223 having a bullet diameter of .224 inches and 243 having a bullet diameter of .243 inches.

223 is primarily used for varmint hunting and target shooting. It has a lightweight bullet with a high velocity, making it accurate for shooting small animals like prairie dogs and groundhogs. On the other hand, 243 is a popular deer hunting caliber due to its larger bullet and higher energy, making it suitable for taking down larger game.

When it comes to ballistics, 223 has a muzzle velocity of around 3,000 feet per second, while 243 has a muzzle velocity of around 2,900 feet per second.

On a side note, another guy to compare the 243 with is the 308; you can see us compare the two here.. While both have a relatively flat trajectory, 243 has a slightly higher recoil due to its heavier bullet. However, the added recoil can also provide better accuracy and stopping power.

In terms of advantages and disadvantages, 223 is often praised for its low recoil, affordability, and high accuracy. However, some may argue that it lacks the power and versatility of other calibers. On the other hand, 243 is known for its versatility, able to take down a wide range of game, but it can be more expensive and have a heavier recoil.

When it comes to hunting, 243 is typically the better choice as it has more power and is suitable for larger game like deer, elk, and hogs. 223 is recommended for smaller game like prairie dogs, but it can also be used for hunting coyotes and other small predators.

In conclusion, while both 223 and 243 have their own strengths and weaknesses, 243 is generally considered the better choice for hunting due to its higher energy and versatility. However, 223 is still a popular caliber for target shooting and varmint hunting. Ultimately, the choice between the two will depend on the shooter’s preference, intended use, and the game being hunted.
