When shopping for 9mm ammo, two bullet weights you’ll commonly see available are 115 grain and 124 grain. If you’re newer to shooting, you may be wondering what the difference is between 115 grain vs. 124 grain and which is the better option.<\/p>\r\n

Today we’re looking at 115 grain vs. 124 grain 9mm ammo so that you know which you should be buying.<\/p>\r\n

What is the Grain of a Bullet?<\/h2>\r\n\r\n\r\n\r\n

Grain is a unit of measurement of mass, with an ounce being equal to 437.5 grains. When talking about ammo, grain is referencing the weight of the bullet of a cartridge. This is the weight of just the projectile that leaves the barrel, not the entire cartridge. We\u2019ve previously covered bullet weight<\/a> in depth if you\u2019d like to learn more.<\/p>\r\n\r\n\r\n\r\n

115 grain (left) and 124 grain (right) 9mm rounds look almost identical.<\/figcaption><\/figure>\r\n\r\n\r\n\r\n

The difference between 115 grain vs. 124 grain 9mm ammo is the weight of the bullet, with 115 grain bullets being lighter than 124 grain bullets.<\/p>\r\n\r\n\r\n\r\n

Because the bullets weight different amounts, the two rounds are loaded to different pressures.\u00a0Generally, the heavier bullet will travel more slowly than a lighter bullet. For example, we can look at the differences in muzzle velocity in rounds from the same manufacturer with different bullet weights:<\/p>\r\n\r\n\r\n\r\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t
