What Is The Difference Between Ss109 And M855?

M855, also known as “green tip” ammunition, is a type of armor-piercing bullet. It is most often used in 5.56×45mm NATO firearms and can also be used in .223 Remington and 5.45×39mm firearms. SS109 is similar to M855 but has a steel core instead of a lead core.

This makes it slightly more effective against hard targets like body armor.

When it comes to ammunition, there is a lot of confusion out there about what is what. One common question is what the difference is between SS109 and M855. Both are types of 5.56x45mm NATO cartridges, but they are not the same thing.

Here’s a breakdown of the differences: The SS109 cartridge was developed by FN Herstal in the late 1970s and was adopted by NATO in 1980. It uses a 62-grain bullet and has a muzzle velocity of 3,025 feet per second.

The M855 cartridge was developed by Remington Arms in the early 1980s and was also adopted by NATO. It uses a slightly heavier 77-grain bullet and has a muzzle velocity of 2,970 feet per second. So, what does all that mean?

The main difference between the two cartridges is simply their bullet weight. The SS109 has a lighter bullet, which means it will have less recoil and be easier to control on full-auto weapons like the M16A2 rifle. The downside is that the lighter bullet may not penetrate as well as the heavier M855 round.

The M855 round, on the other hand, will have more recoil but its heavier bullet will penetrate better than the SS109’s lighter one. So, if you’re looking for ammo that penetrates better, then go with M855; if you want something that’s easier to control on full-auto, go with SS109.

M193 Vs Ss109

M193 Vs Ss109 The 5.56x45mm NATO (official NATO nomenclature 5.56 NATO) is an intermediate cartridge developed in the United States and originally chambered in the M16 rifle. Under STANAG 4172, it is a standard cartridge for NATO forces as well as many non-NATO countries.

It is derived from, but not identical to, the .223 Remington cartridge.[1][2] The SS109/M855 was adopted as the standard U.S./NATO ball ammunition in 1980 and has remained so ever since.[3]

The SS109 bullet utilizes a steel penetrator whereas the older M193 round did not.[4] The SS109 also features a thicker copper jacket than the M193 resulting in increased penetration of light barriers such as sheet metal or glass.[5] The major downside to this heavier bullet is that it has less velocity than the M193 resulting in slightly less range and accuracy.

Is Ss109 Armor-Piercing?

No, SS109 is not armor-piercing. It is a soft point bullet, meaning that the tip of the bullet is designed to expand upon impact to increase damage. While this can penetrate some light armor, it is not designed to penetrate heavy plate steel or Kevlar body armor.

Is Ss109 Same As Green Tip?

No, SS109 is not the same as Green Tip. While both types of ammunition are designed for use in AR-15 rifles, they serve different purposes. SS109 is a NATO standard cartridge that is used in military applications.

It is also known as the M855 cartridge. The “SS” stands for “special surprise,” which was the original intent of the design – to create a bullet that would penetrate light armor and still be effective against enemy soldiers. The SS109 round has a 62 grain steel core bullet with a lead alloy jacket.

It is designed to yaw (or tumble) after impact, causing maximum damage to soft targets. Green Tip is a type of ammunition that is often used for target practice or plinking. It gets its name from the green paint on the tip of the bullet, which indicates that it is made of copper instead of lead.

Green Tip rounds are generally lighter weight than SS109 rounds and have less penetration power.

Which is Better M193 Or M855?

M193 and M855 are both types of 5.56mm ammunition used in AR-15 rifles. They are very similar, but there are some key differences that make one better than the other in certain situations. M193 is a lighter bullet that is designed to fragment at shorter ranges.

This makes it ideal for close-quarters combat or self-defense situations where you need to worry about overpenetration. M855 is a heavier bullet that is designed to penetrate deeper at longer ranges. This makes it ideal for hunting or long-range shooting situations where you need the extra penetration to reach your target.

So, which is better? It really depends on what you’re using it for. If you need a light, fast bullet for close-quarters combat, then M193 is the way forward.

If you need a heavy, penetrating bullet for long-range shooting, then M855 is the better choice.

Does Ss109 Have Steel Core?

No, SS109 does not have a steel core. It is a lead core with a copper jacket and is designed for high-velocity impact and penetration.


The difference between SS109 and M855 is that SS109 is an improved version of the M855. The M855 was originally designed for use in the Vietnam War, but was never adopted by the US military. The SS109 was developed in the 1980s and adopted by NATO in 1983.

It is now the standard ammunition for most 5.56mm rifles.
