How Many Grains In A Pound? (Reloading Guide)

Are you wanting to make some DIY bullets and need to know how many grains are in a pound of powder? More importantly, how many how many grains in a pound of powder so you can calculate how many bullets you can make?

One pound of powder equals about 7,000 grains. There is actually no grain. Bullets contain either wheat or oats. To determine the number of bullets you can load, you would take the number of grains needed for the specific type of bullet and divide by 7000.

When purchasing ammunition, you should do all the research you can before making the purchase. Many people purchase ammunition that is functional with the firearm or doesn’t fit their needs, and they end up trying to sell it or it’s left in the box, where it won’t be seen again. This article will give you information on ammunition, which will include the measurements and what ammo is good for what situation.


Normally, the measurement of the bullet is referred to as the diameter. The diameter is also known as the caliber, which is one of the most important specifications to remember. The caliber is normally referred to the cartridges of the gun, which is measured in hundredths of inches or millimeters. This is a list of the common calibers that you will most likely see.

The common Calibers measured in millimeters:

  • 9mm
  • 10mm

The common calibers measured in inches(Hundredths):

  • .22
  • .380
  • .38
  • .40
  • .44
  • .45


Grain refers to the mass or weight of the ammunition and is a unit of measurement. One grain can only way 1/7000 of a pound or 0.064 grams. In one pound there are 7,0000 grains or 437.5 grains in one ounce. If a bullet is 230 grains, then that means that it is a .45-caliber weight bullet. Another example is that a 115-grain bullet would weight nine millimeters.

If you want to purchase some gunpowder, then it will highly depend on the type of powder that you are trying to purchase and the distributor that you are buying it from. At most establishments, a pound of gunpowder can range from $15 to $20 per pound and if you are purchasing it in bulk, then you may be able to get it for a 10 to 15% discount.

Purpose For Ammo

When you are trying to choose the type of ammo that you are buying, then you should think about what the ammunition will be used for. There are different types of ammunition that is designed for hunting, target shooting, competition, and personal defense.

The ammunition that is made for hunting and personal defense is designed to have increased velocity, a heavier bullet and a bullet that is designed to spread when it hits its target. These types of bullets are normally sold in containers in small quantities and is a bit more expensive. The hunting and personal defense ammo has more recoil, which is more commonly known as “kick.”


Competition ammo is designed for the specific type of competition and some have great accuracy while others have more speed. This is because for some events need to have better accuracy, which may lead to a more expensive bullet design and more expensive.

Many people that are shooting in competitions look for ammo that has less recoil. But you should know that competition shooters normally modify their guns so that it will work with different ammunition. Just know that some ammunition doesn’t work for all types of firearms.

Target Shooting

This ammunition is generally used most of the time. This can be found being sold in bulk at sporting good stores and unlike competition ammo, it can be used for a wide variety of firearms but doesn’t have as much recoil as the hunting or self-defense ammunition does. Target ammunition is the best type of ammo and is mostly used when beginners are using it for typical shooting practice.

Purchasing Powder Problems

When you are going to purchase ammunition, there are a few things that you should think about before making your home a place filled with new ammo. One thing is that you should purchase only a small amount of ammunition. Many stores will not accept a return of ammunition, so you need to know if the ammo is functional with your firearm before you commit to make the purchase or you will be stuck with a ton of ammunition that you have to try and sell to another person.

Next you should keep in that some guns have to have a specific type of ammunition. Just because the ammunition works for one firearm, doesn’t mean that it will work for all of them.

Accuracy is another important thing that you should think about. There are bullets that shoot better for certain firearms. Even if you buy the best ammunition, it may not shoot well from the barrel. You may learn that a certain type of bullet may work better for your firearm than what your friend that thinks they know everything said was bad.

Lastly, you should consider the source of where you get your ammunition from and that it is from a reputable source. There has been times when the ammunition destroyed a gun and this can happen from even the best well-known manufacturers.

Choosing Powder For DIY Bullets

When it comes to making your own bullets, a lot of important questions can come up and have to be considered. One of these is the number of grains that are in a pound of gunpowder, but that is not the only one.

Below is a breakdown of the 5 most commonly asked questions when it comes to gunpowder. Now, when it says gunpowder, it means the powder that can be bought for people who make their very own bullets.

The main thing to keep in mind is that some of these numbers can be different. They can be different because of the type of powder that is being used. Another thing that can affect some of the answers below is the type of bullet.

These are just some of the basic answers for what you’ll generally find, they are still useful for you.

Frequently Asked Questions

Here are some of the most common questions I’ve seen around the similar subject.

How many grains are in a pound?

The grain is actually a weight measurement itself, which means to figure out the number of grains in a pound is a simple conversion of weight. 1 pound equals 7000 grains, and no matter what the grains come in, they will still be the same amount for 1 pound.

The type of powder also does not play any kind of roll in the number of grains there is in a pound. Each grain of gunpowder, no matter the type will be the same weight, which means the same number per pound.

Now, while there are lots of easy to use weight converters that can be found online to do the conversions, if you’re crazy like me, we like to do the conversion themselves.

There are two different methods that can be used for this conversion.


lb = gr * 0.00014285714

lb = gr / 7000

The number in the first equation comes from 1 grain being 0.00014285714 pounds.

How many grains of powder in a 1 pound can?

A 1 pound can of gunpowder comes with 7000 grains of gunpowder.

Now, this may sound questionable since different types of powder have different weights, but it is the truth.

When it comes to buying a 1 pound can, the number of grains is 7000. While there are different weights, the amount of grains you get from a 1 pound can is the same because the difference in the weight is so very small.

With the small amount of weight difference, the same number of grains will be in each can no matter the type. That does not mean you will end up using all 7000 grains, because no one can load bullets and not lose some grains.

The number of bullets will also change because each one uses a different amount of gunpowder. Not even a professional can manage to make bullets without losing some of the grains of gunpowder they use in the process of making them.

How many bullets can you load with 1 pound of powder?

The number of bullets that can be made out of 1 pound of gunpowder will depend on the size of the bullets. The box that the bullets come is will state the number of grains that are needed for each one.

There is a simple equation that can be followed in order to find out how many bullets you can make. You have to know what bullets you are going to be making first. The equation is to divide 7000 by the number of grains per load that bullets require.

An example of this is that 6350 rounds can be made for .25acp bullets out of 1 pound of gunpowder. As for a 50BMG, a person could get 28 to 32 rounds. 300 rounds can be made for a .223, and about 1500 rounds can be made for a 9mm or a 45acp. These are just one person’s amounts, but they can vary for different people.

How much does a pound of gunpowder cost?

The price of gunpowder in today’s day and age is rather low, and the price is going to be different depending on the type of gunpowder being bought. Another thing that plays into the price is what is going on in the world.

Most average from around $25 to $30 for every pound. The person buying the powder can change the price, such as the government gets cheaper. The government tends to buy their gunpowder by a keg, which weighs 25 pounds.

They can buy a keg for around $4 to $5, but that is for the whole 25 pounds. If they spend $5 for 25 pounds, then 1 pound costs the government $0.20, which is not very much.

Back when the revolution was happening though, the government had to pay $25 for one keg, which means they were paying $1 per pound of gunpowder. This shows things can change the cost because of the amount of demand.

What does 1 grain of gunpowder weigh?

The grain itself is a unit of measurement, but people often do not consider it as one. To make it simpler to understand, 1 grain of gunpowder weighs 0.065 grams. This means 1 grain is only 1/7000 of an avoirdupois pound.

A lot of people do not take into consideration how much 1 grain at a time weighs ironically because of how little it weighs. People often think more about how much gunpowder is needed for the bullet and how much that specific amount weighs.

An important thing to keep in mind when calculating how much gunpowder weighs is that different types of gunpowder tend to have different weights. Not all grains are created equally, some are thicker, fatter, and more blessed than others.

RESOURCE: See this PDF of the Volume Measure Density for reference.

Different gunpowder is made up of 3 different things: a fuel, an oxidizer, and a stabilizer. The gunpowder will have different things that fit into these 3 things, and each has its own weight.

How many grains in a pound of smokeless powder?

There would still be 7,000 grains in one pound of powder, smokeless or not.


Just to quickly recap, there are roughly 7,000 grains per pound of powder.

Grains are simply a measure of weight, a unit to measure weight. For example, a 120g bullet weighs 120 grains.

Unless you’re getting into the reloading aspect of firearm ammunition, you won’t have to ever think much about grains since the grains are listed on any ammunition you would buy.

I hope this post on how many grains are in a pound helped you with your reloading process.

Have you ever made your own bullets and had to measure in grains before?
