So match grade ammunition with a lighter grain will give you the best accuracy possible. The case for a lighter weight but faster bullet Those who advocate for a lighter but faster bullet will point to the fact that the formula for kinetic energy is 0.5mv^2 (1/2 of the mass x the square of the velocity); meaning that a lighter bullet at a higher speed will carry more kinetic energy than a heavier bullet at lower speeds. Some commercial ammo is loaded to Higher pressures. (Sir Isaac Newton wins again.) In others, such as Remington's HTP loads, penetration was the same but the heavier grain weight didn't expand or didn't expand as well. A 9mm bullet weighing exactly 124 grains. Other people believe that the bigger the wound channel, the more rapid the blood loss and thus incapacitation will be, and thus more reliable expansion is more desirable. The Federal 115-grain 9mm ammo has a muzzle velocity of 1,180 fps, while the larger bullet is propelled at 1,000 fps. But keep in mind, that this is situation dependent and there is no definitive yes or no answer. The same 180-grain bullet with a muzzle velocity of 2,450 fps will perform almost identically. 9mm bullet weights range from 115 to 147 grains and velocities from 1,200 to 1,000. The 124 grain bullet loaded to higher pressures (+P) will have a higher velocity than the standard load with a heavier 147 bullet. Anyhow, a 115-gr projectile has a mass of 7.45 grams (0.00745 kilograms) and 1150 feet per second (ballpark velocity for 115-gr 9mm bullets) works out to 350.52 m/s. In fact, 1 ounce is equal to 437.5 grains, just to give you an idea of how small it is.For another comparison, 1 gram is equal to 15.43 grains. In reverse, higher grain size bullets can be a better choice for self-defense. For instance, most 9mm loads are either 115, 124, or 147 grain, but occasionally you might see a 95 grain, 110 grain, or some other oddball load.

However, they are inexpensive, reliable brands that should be your first choice when selecting ammo for practice or competition. .45 ACP doesn't result in quicker incapacitation from blood loss, and .44 Magnum will not take your head clean off. Heavier bullets are slower and are often subsonic, meaning an even greater noise reduction is achieved if shooting, say, 147-grain 9mm ammunition (already subsonic) or 230-grain.45 ACP ammunition, also subsonic. Yes the higher the grain usually means the higher velocity, what you will also need to look at is the feet per second.  A firearms education site built on trusted content by firearm enthusiasts and members of the special operations community.

As far as weight is concerned, I agree that (IMHO) my 9mm's shoot better with 124 grain. A lighter bullet will hit the target at a faster velocity, thereby guaranteeing more hydraulic pressure inside the body cavity and therefore more dramatic expansion at the cost of some penetration. Have a look, for instance, at Lucky Gunner Labs ammunition tests. As you can see by these back-of-the-envelope calculations, a heavier-for-caliber projectile has slightly more momentum than a lighter-for-caliber projectile sitting over the same charge of powder. For self defense, a heavier bullet gives you a better chance at stopping a threat. Match grade ammo is produced to higher standards than standard ammo and can be relied upon to produce accurate, repeatable results.

In other words, a skinny bullet of a given weight tends to penetrate better than a fat bullet of the same weight, because it concentrates the same force on a smaller area of the target. 9mm rounds are better with lower bullet grain since they often have a higher muzzle velocity, lower recoil, and are relatively more accurate. Your email address will not be published. A 147-gr projectile with a velocity of 950 fps (ballpark for 147-gr 9mm) would have momentum of 2.757 kg m/s.

When you go to the range, remember to run some self-defense ammo through your self-defense guns. Speaking of distance shooting, that segues nicely into our next shooting scenario.
