Importance of Accurately Measuring your Gunpowder

Before talking more about powder scales and more specifically mechanical powder scales, first you need to understand why it’s important to accurately measure and weigh your gunpowder. For shooters that load their own shells, having a gunpowder scale is critical to ensure accuracy and savings.

As said before, gunpowder affects the firing characteristics of a shell. Inserting the exact amount of gunpowder ensures that your bullet has a good firing characteristic. In critical situations, having a bullet that’s accurate and fires well is a lifesaver.

Another reason would be to reduce gunpowder waste and save money. If you put excess gunpowder, you’ve just wasted that powder. Wasting gunpowder means that you’re slowly losing the money you saved by loading your own shells.

If saving money is the prime reason you reload your ammo yourself, then by all means get a high quality mechanical beam scale for reloading.

Besides cost savings and firing characteristics, a lot of shooters prefer to have direct control of their bullet’s manufacturing quality. If they reload it themselves, that means they can closely monitor the quality and craftsmanship of each loaded bullet.

If you’re a gun enthusiast and relate to any of the reasons above, then it might be a good idea for you to buy a high quality mechanical powder scale.

How to Choose the Best Mechanical Beam Powder Scale for Reloading

Choosing the right mechanical powder scale for your reloading needs heavily depends on what you need and how much you’re willing to pay. If you’re an enthusiast, your needs might be different compared to the casual weekly shooter.

Because of that, it’s very important for you to analyze what you need, what situations you’re likely to face, and what you’re comfortable with using for a long time. Because a powder scale is a decent investment, it’s recommended to buy the best and cry once rather than buying the cheapest and crying later.

In general, there are 5 things that people tend to analyze and pay attention to when buying a powder scale for reloading. These things include

  • Type
  • Sensitivity
  • Capacity
  • Durability
  • Price

Type of Scale

There are two types of powder scale for reloading that you can purchase: a digital one and a mechanical balance beam scale.

Digital powder scales or frequently known as an electronic scale measures your gunpowder electronically. Then, they output the weight in numbers on their LCD screen. Meanwhile, a mechanical beam scale allows you to weigh your powder manually using a counter-balance weight and a balance beam.

Some find the manual beams to be more accurate and more durable while others prefer digital scales for their ease-of-use and quick to read numbers. It’s really just a question of what you like best and what you’re comfortable with using on a daily basis.

When deciding what type of scale to use, make sure to account for your usage needs and other factors such as weight and versatility. Don’t be fooled into buying something you don’t need just because it looks nice and ‘might’ be useful in the future.


No matter which type of scale you choose, you want to look for one that has a high sensitivity. An ideal number to shoot for would be 1/10 grain accuracy. This will ensure that you’ll be able to measure with great precision and keep wasted powder to a minimum.

Besides sensitivity, make sure that the labels and weight indicators are easy to read an interpret. A highly sensitive scale will be pretty useless if you can’t read how much your gunpowder weights correctly.

However, be mindful that the sensitivity of a mechanical scale highly depends on it’s beam scale. It also depends on your ability to correctly read the numbers on the scale. In general, a mechanical scale will not be as sensitive as a digital scale but will be able to maintain that sensitivity better in poor environments.


Capacity is the amount of powder you can weigh at once with your scale. Whether you are planning on reloading a small number of shells or a big batch, flexibility with how much you can weigh is important. Make sure you get a scale that has sufficient capacity for your weighing and reloading needs.


Durability is very important for just about any product, but it becomes even more important for items that you use regularly. If you’re a shooter who likes to reload your own cartridge, having a durable and long lasting powder scale is very important.

Having a durable powder scale helps you save money because you won’t have to replace it often. Besides, you’ll also need a durable scale if you frequently bring your scale with you on the move. Mechanical scales usually have better durability compared to digital scales because it doesn’t have many electronic components that are easy to break.

However, keep in mind that the even the best powder scale will quickly fall into disrepair if not cared for correctly. In general, clean the scale after each use and store it in a cool and dry place when not in use.


Price is a top concern for almost any buyer. Most of you want the highest quality scale, but you also want to get one that’s fits your budget right? Because of that, when deciding which powder scale to buy, you have to weigh in the benefits of extra features and durability with the extra cost associated with it.

Sometimes, buying the cheaper brand is better if you don’t need the extra features that much. This way, you can allocate your budget on more important items that you may need. But for some, it’s important to get the best quality scale you can buy for their accuracy and durability.

Frequently Asked Questions when Buying a Powder Scale

Here are several frequently asked questions (FAQs) by buyers when they’re looking for a powder scale. See if your question has already been answered!

Q: Why reload your own ammunition?

Answer: People reload their own shells for a variety of reasons, the most prevalent of which are cost savings and quality control. However, once they get started, many people like the process of reloading their own ammunition. This is most likely owing to a closer relationship with their bullets.

There’s something fulfilling about firing a bullet that you built from the ground up. From weighing the gunpowder through inserting the primer and eventually firing the shot, everything is done by hand.

Reloading their own ammo can be a relaxing and stress-relieving experience for some people. You essentially sit down, put on some soothing music, and spend your time making your own ammunition. Some people may find this to be a worthwhile way to spend their free time.

Of course, these scales aren’t the only equipment you’ll need while reloading your own ammunition. Hand priming tools, reloading dies, and reloading presses are examples of reloading tools.

Q: Why you need a reloading scale?

Answer: If you’re going to reload your own shells, you’ll need a high-quality reloading scale. You won’t be able to correctly measure the amount of powder in each cartridge if you don’t have it.

Furthermore, being unable to precisely assess the amount of gunpowder on hand can lead to waste. The savings you obtain from reloading them yourself will be wiped off. As a result, having a dependable and accurate reloading scale is critical when reloading your own ammunition.

Q: What is “zero out” on a scale?

Answer: When it comes to scales and weighing objects, the term “zeroing out” is widely used. In simple terms, zeroing out refers to resetting the scale to zero by accounting for weights that should not be measured.

Using a metal tray to contain the gunpowder you’re trying to weigh is an example of this. You simply want to weigh the powder; you don’t want the weight of the metal tray to influence the results.

To exclude the metal tray from the equation, you must first zero out the scale by taking into account the weight of the metal tray. A button to zero out a digital scale, such as the ones we discussed in this article, is frequently present. Those who don’t usually have a complex procedure specified in the manual.

Q: Why does everyone measure powder in grains?

Answer: The reason for this is simple, grains are a lesser unit of measurement than grams. Using grains rather than grams, people can more correctly determine how much gunpowder should go into a round. To make rounds with the least amount of difference in performance, make sure they all have the same amount of charge.

One way of having the smallest variation between batches is to use the smallest measuring standard, which in this case is grains compared to grams.

For your information, 1 gram equals 15 grains. As a result, saying 10 grain of gunpowder is easier than saying 2/3 gram. People like to utilize grains to speed up the measuring process, despite the fact that it is not an International Standard measurement but rather an imperial and US-specific unit.

Q: What else can I measure with the reloading scale other than powder charge?

Answer: A reloading scale is basically just like any other scale on the market. The only difference is the capacity and the accuracy of it to be able to measure in grains accurately. Because of that, your reloading scale can be used to measure just about anything.

However, if you’re a shooting aficionado that’s going to use this scale frequently it’s important to not use it for other purposes. Even the smallest amount of residue from other substances may corrupt your gunpowder and make it unusable.

Q: Digital vs mechanical reloading scale – Which to choose?

Answer: The choice between a digital and mechanical scale depends on what you’re comfortable with using. many people would pick a digital scale simply because it’s the easiest to use. Once you zero out the scale, you won’t have to do anything except put your powder and see how heavy it is.

Some type of combination dispenser-scale also automatically dispenses powder into the scale. You simply choose the amount of powder you wish to have and it will provide that for you.

However, digital scales are very sensitive to the environment around you. Sometimes, it’ll fail to zero out or have slight variations in measuring accuracy due to humidity and electrical current errors. If you want a bulletproof scale that you can store anywhere without too much worry, choose a mechanical scale.

These are much easier to zero, and provide less issues for you. They’re also a lot more stable and resilient to adverse environments. Plus, you don’t have to worry about any kind of power source. Sadly, the overall accuracy of a mechanical beam scale is not as high as a digital scale due to human error and poor visibility.

Q: How accurate are mechanical reloading scales?

Answer: Mechanical reloading scales have incredible accuracy. Even though most people say that they’re less accurate compared to digital scales, it’s mostly due to human error when identifying the numbers on the beam. Sensitivity wise, it’s close to a digital scale.

However, mechanical reloading scales are more stable and accurate in adverse conditions. Vibration and moisture will hamper digital powder scales more compared to mechanical ones.

Q: How to take care of a reloading scale?

Answer: Like all tools, it’s very important to take good care of your reloading scale so that they’ll last for a long time. If you don’t take care of them, they’ll lose accuracy and sensitivity due to accumulating rust and dust.

If you buy a mechanical powder scale, you’re lucky they aren’t as hard to maintain as digital scales. They’re more rugged and easier to store due to having no electronic parts. However, this doesn’t mean that you can neglect to take care of them.

For starters, you should store your scale in a place that’s secure and out of harms way. This reduces the chance of the scale being knocked over or bumped against. The more wear and tear you scale receives, the lower it’s accuracy. You should also store it in a place where it’s dry and cool to prevent rusting. This is important for mechanical scales that have a lot of moving parts.

You should always clean your scale after using it to prevent rusting and other types of harmful residue. This can be done by simply wiping down the scale after every use to eliminate residue. You can even use alcohol rubs and soap to clean the tray if you’re not sure if the residue has been eliminated.

Simply treat your mechanical reloading scale with the utmost respect and it’ll continue serving you accurate measurements for years to come.

Q: What is the best mechanical powder scale for reloading?

Answer: Like everything, the answer to this question is… it depends. Which mechanical powder scale to choose highly depends on what you like, what’s your budget, and what you need. All of the tools listed in this review are high quality mechanical scales that are top notch. However, all of them has different strength, weakness, and price points.

It’s up to you, the buyer to choose the best one depending on your needs and wants. However, we still recommend the Hornady Lock-and-Load as one of the best if not the best mechanical reloading scale due to it’s accuracy, versatility, and value for money.
