There is a specific design for each gun for a particular purpose. The sniping guns have different models, the hunting guns have different, and the army guns have others. And not only that, these guns use other ammo of various sizes. And if you have an interest in these guns, you must have the information about every minute detail about arms and bullets.

If you are a newcomer in this field, then you might be looking for some information! The most confusing thing is to differentiate between the features of two guns or bullets. One of the fascinating questions that arise in a newbie’s mind is, “What is the Difference Between 115 Grain and 124 grain 9mm ammo?” Don’t worry at all because this information post has the answer to your valid question.

Difference Between 115 Grain and 124 Grain 9mm Ammo

If you take a look at the bullet description, you will know that there is no difference in the bullet’s size. The shot with 115 grains and 124 grains has an equal bullet size and shell shape. There is nothing to do with the gun powder. And nothing wrong with the shell material. Then what is the significant distinction between these two? Well! Those who are unaware of the grain are the fine particle present in the bullet that provides a specific weight to the unit. It is the smallest unit in which we can quantify mass. 

There are several grains in one ounce, so you can imagine how small grain can be! But the answer does not end up here; there are many differences in these bullets having different grain numbers in their shells. Some of the significant differences are as follows:

Weight of the shot

It’s the number of grains that decide the weight of the bullet. The mass does not rely either on the built material of the shot or on the gun powder. So the grains are playing a significant role in defining the weight of the bullet. The higher will be the number of grains, the heavier the shot will be. 

It points out that the bullet of 9mm with 124 grains is heavier than the bullet having 115 grains in it.

Projectile Motion

When you press the trigger and fire the gun, the bullet comes out of the nozzle and covers some distance. After covering a specific length with a constant height from the surface, the direction of the shot starts going down towards the earth gradually. It is physics, and this type of motion is known as projectile motion. When we go through this factor, we will find out that the heavier objects move towards the earth quickly compared to the lighter ones. It is because they are unable to cover the long-distance as compared to the lightweight things. Hence, the second significant and observable distance will be the range of both bullets.

Make a test fire and check that which bullet has covered more distance. The lighter one will cover more length as compared to the heavier ones.

Recoil Difference

When you fire a bullet, you have to hold it tight to avoid any backward movement of your shoulder. But that force generated in the result is far greater than your strength. So you might have experienced a slight back-shifting movement of your arm. It is also a physics principle. We all know that action and reaction are the same but are opposite in direction. The same case is with the bullet’s firing. The gun fires the shot, and the shell moves forward, which is the action. As the result of this action, the weapon’s movement in the backward direction is the reaction.

Now, make it very clear that the gun has to generate more force to fire the heavier bullet than fire it lighter. Hence, the recoil of 124 grains bullet will have a high recoil rate. And to manage that, you have to make sure that you have a firm grip on the gun, a steady arm, and a good shooting stance.

The momentum of bullet

The momentum that comes in generation due to the gun force is also a significant and decisive factor that helps to differentiate between 115 grains and 124 grains 9mm bullets. Let’s keep it very simple with an example of a car and truck. What do you think a car has more mass or a car? It’s the truck! But if they both are moving at the same speed and hit a wall, then which will cause more damage to the wall? The answer remains the same; it’s the truck because of its momentum.

The same is the case with these two bullets of 115 grains and 124 grains. The bullet with a heavier weight can cause more damage and penetrate more than the lighter one. Here is the link for a better understanding of the phenomena as mentioned above:
