9mm how much powder

More charge means a bigger boom. But different bullets need different charge weights per load or per round to be used safely. After that, you can carry out the necessary calculations to know the gunpowder load in every bullet.

You should also have a reloading manual handy before you start to load your own ammo. These books are made by gunpowder manufacturers who know how many grains of powder you should put into different calibers of bullets. For instance, 9mm bullets some of the most common for self-defense come in , , and grain gr varieties.

But none of these take over grains of gunpowder! Instead, the most common charge weight is 5. That means each bullet usually only takes 5 grains of powder for loading.

In the above example of using charges of 5 grains, you could make 1, 9mm bullets since each only takes 5 grains and 1 pound of gunpowder has 7, grains. Your source may vary, but most folks use charges of 25 or so grains. Remember, each bullet type takes a different type of powder charge.

We recommend the Lyman 50th Edition Ammo Reloading Book, which has a ton of charge info you can use for popular bullet types. It can also help you with powder conversion, offering excellent value for money.

Alternatively, check gun forums and posts — hobbyist shooters on a good forum can provide their expertise with a helpful post or two and ensure you load your rifle correctly.

On the other hand, if you overpack your bullet by filling it with too many grains of gunpowder, you could cause it to explode too violently, leading to an accident and possibly injuring yourself. Heavier bullets typically require more grains of gunpowder or require larger grains of gunpowder to produce a suitable explosion. Lighter bullets require fewer grains of gunpowder on average.

But this can vary dramatically from bullet to bullet depending on their materials, what kinds of guns they are used with, and more. Bullet powder grains can also vary in terms of size.

When it comes to gunpowder, smaller grains have more of their surface areas exposed to the ignition substance. As a result, they typically burn faster than larger grains. Naturally, ammunition that uses smaller grains for its charge weight will explode from the barrel of a firearm faster and with higher initial velocity.

However, this earlier burning mostly terminates before the bullet leaves the barrel of a firearm. Larger grains are the opposite. Larger grains, therefore, may be better if you need to ensure your bullet travels far and accurately without losing velocity. Archived Questions Goto Qn. How many grains of gunpowder are in a 9mm bullet? Currently voted the best answer. Bullets do not contain gunpowder.

Most bullets consist of a lead core inside a copper alloy jacket. Cartridges consist of a cartridge case, or shell, the bullet, a primer, and a charge of gunpowder.

In the case the the 9mm pistol cartridge the charge can vary between 4 and 9 grains, depending on the propellant. A 9mm rifle cartridge may hold 95 grains of propellant.
