What Is .40 S&W Ammo Good For?

A key asset to .40 caliber ammunition is that it’s a middleground round. While some consider it an alternative to the .45 ACP, others view it as a useful round all on its own.

The .40 Caliber round is more powerful and has more downrange energy than its 9mm counterpart, although a 9mm pistol with the same size may be able to hold more rounds since the cartridge is smaller. While a pistol chambered in the .40 S&W holds more rounds than it can with a .45 ACP, its muzzle energy is significantly higher than that of .40 caliber ammunition.

As a result of extensive testing by the FBI and many other agencies – which led to widespread adoption of the .40 S&W among police agencies – it strikes the right balance between muzzle energy and magazine capacity. The U.S. Coast Guard has also adopted the .40 S&W as their primary issue handgun.

Types Of .40 S&W Ammunition:

There is a vast array of bullet types and loads available in .40 S&W ammunition, the majority of which are available in bulk .40 caliber rounds. Some of the most popular .40 caliber rounds include:

Full Metal Jacket (FMJ):

Typically, FMJ bullets are enclosed in a harder metal to maintain their shape as the projectile travels toward its target; FMJ bullets are the most common round for target shooting in most calibers.

Total Metal Jacket (TMJ):

A TMJ ammunition protects shooters by covering the lead bullet in a harder metal, while leaving the FMJ exposed at the base; some ranges require TMJ ammunition.

Jacketed Hollow Point (JHP):

.40 S&W JHP ammo is often used for self-defense and duty; JHP bullets are enclosed in a metal casing but have a hollow point that helps with expansion, wound size, and stopping power.

Brass Enclosed Base (BEB):

Brass-encased BEB bullets limit lead exposure when shooting; many of them were designed specifically for controlled environments and have non-toxic primers.

Complete Metal Jacket (CMJ):

The CMJ bullets are encapsulated with lead, limiting exposure; they also don’t release as much smoke as TMJ bullets.

Frangible Bullets:

Fangible bullets, made up of copper powder and shatter on impact, are often used when over-penetration is a concern. This type of bullet not only protects bystanders but also eliminates ricochets.

Frequently Asked Question

What is 40 S&W ammo?

It was developed to bridge the gap between .9mm and .45 ACP after the FBI requested a new round.

Which is more powerful, 9mm or 40 S&W?

Although the .40 S&W has a greater amount of power, it does have more recoil (although not as much as the .45 ACP), and it is often described as “snappy.”

Are there any differences between 40 Cal and 40 S&W?
