In general, grain is a unit of measurement of mass. Grains are commonly used to measure the mass of bullets and propellants. For ammo, grainmeanstheweightof thebulletofacartridge.
The grain of a bullet refers to the weight of the projectile portion of the ammunition. It is a unit of measurement commonly used in the firearms industry, especiallyforsmallarmsammunitionsuchashandgunsandrifles.
One grain equals 1/7,000 of a pound or 1/437.5 of an ounce. Grain is not the weight of the entire round of ammunition, but just the projectile that leaves the barrel.

There isonlya9-grainweightdifferencebetweena115-grainand124-grainbullet. But the shooters will often prefer the 124 grain over 115 because there is less felt recoil,andtheycangetfollow-upshotsontargetquicker.
Because of the different bullet weights from the same manufacturers, you can see the differences in muzzle velocity. We are sharing the table below with the comparisonof2differentbulletweightsfromthesamemanufacturer.

115 Grain Vs. 124 Grain 9mm Ammo - Performance & Accuracy Differences
When comparing the accuracy of 115-grain and 124-grain bullets in firearms, it's important to note that several factors can influence accuracy, such as the specific firearm,ammunitionquality,shootingtechnique,andenvironmentalconditions. However, some differences between 115-grain and 124-grain bullets can affect theiraccuracy.Herearesomepotentialfactorstoconsider:

● Velocity:115-grainbulletstypicallytravelathighervelocitiesthan124-grain bullets, which can make them more accurate at longer ranges due to less dropandwinddrift.
● Bullet design: The design of the bullet can also play a role in accuracy. For example, some 124-grain bullets may be designed with a longer, more aerodynamic shape that helps them maintain velocityandaccuracyatlonger ranges.
Ultimately, the best way to determine which bullet weight is more accurate for a particular firearm is to test both types of ammunition and compare the results. Some firearms may perform better withoneweightoveranother,whileothersmay notshowasignificantdifferenceinaccuracybetweenthetwo.
