Then we checked the reliability, warranty, durability, maximum grain capacity, ease of use, the learning curve for zeroing and use scale accessories, and the price. We are pretty sure that you will find here the scale that works best for you.
Redding – #2 Master Scale
Redding is a reloading equipment company that has been around since 1946. It makes its products right here in the USA and offers a lifetime warranty on them unless they were misused or handled carelessly.
Redding’s No. 2 Master scale features a 505 grain capacity with a two counterpoise system. The base is sturdy and durable. It is good practice to place your scale on a piece of glass as it provides an even surface; the scale holds zero better when placed on the glass. The scale does not come leveled. You have to turn the adjustment screw on the base to level it. Leveling the scale is the most important thing to do before you start using it. Otherwise, it won’t be accurate.
The scale base has a part on its left-hand side that looks like a tower with an opening inside of it. There is a magnet in the opening where you place the copper tab of the beam. The magnet is a braking mechanism for the beam. It helps the scale settle to zero faster. The bearings where you place the other side of the beam are precision-milled by the factory so you should not touch them. The scale includes a powder weighing pan. Learning how to use this scale takes a little bit of time but when you master it, it works like a charm. For more visual info about this scale check out this video.
Pros
- Durable and sturdy
- 505-grain capacity
- Weighing pan included
- Precise to 1/10 grain
- A magnet for an easier zeroing
- Milled stainless steel bearings
Cons
- Better keep a pane of glass underneath it for leveling
- Steep learning curve
- Higher price range
RCBS – M1000 Mechanical Scale
RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. Huntington was an avid shooter, who started to craft his own dies in the back room of his father’s laundry and dry-cleaning business to reload varmint bullets. These bullets were used to shoot rock chucks, so he named them Rock Chuck Bullet Swage dies, later shortened to the ‘RCBS’ that is well known for top-quality reloading tools. RCBS offers a limited lifetime warranty.
The M1000 mechanical scale is another great product from RCBS. It gives users 1,000-grain capacity with +/- 0.1-grain accuracy. This scale is suitable for right or left-handed users alike.
It offers magnetic damping for fast readings and maintenance-free movement. There is a metal tip-proof pan that makes loading powder easy. The scale comes pre-calibrated so you should not have any problems finding zero. However, it is a great idea to place the scale on a shelf at eye level for exact weighing. Reading the scale can sometimes cause parallax. An easy solution is to use your phone and read the scale through it.
Pros
- Sturdy and durable
- Great brand and limited lifetime warranty
- 1,000-grain capacity
- 3 scales in one
- 0.1-grain accuracy
- Magnetic damping
Cons
- Reading the scale can cause parallax
- Very expensive
Lee Precision – Safety Powder Scale
The Lee reloading business started in the workshop of Richard Lee in 1958 with the invention of the famous Lee Loader for shotgun shells. Richard Lee continued innovating his reloading tools and accessories, including scales, under his company Lee Precision. The company provides great customer service and guarantees that if their product breaks within 2 full years from purchase, it will be exchanged or repaired immediately.
The Safety scale is an extremely accurate scale. It weighs powder to 1/20 of a grain. That means it is a little bit hard to settle and the learning curve on how to operate this scale will be steep for a beginner. To achieve accuracy always zero your Safety scale before you start using it. Humidity and change of temperature can affect its calibration.
To calibrate your scale set the main base weight to zero and lock the two smaller weights on the right to zero as well. When that is done the left side of the base should point to the mark on the left base tower of the scale. There is a special thumb screw inside the base which helps with zeroing the scale. This scale is reliable and easy to use once you learn how to operate it. It has a capacity of 100 grains. The only complaint is that there is no way to lock the thumbscrew in place, making it possible to brush it and lose calibration when adjusting the slider position on the beam.
Pros
- Sturdy
- Great brand and warranty
- Very precise, to 1/20 of a grain
- Thumbscrew in the base helps with zeroing
- Capacity 100 grains
- Very good price
Cons
- The learning curve is steep
Lyman – Pro Scales
In the late 1800s, William Lyman, an avid outdoorsman and inventor, created his first product. Since then, the Lyman company has focused on innovation and manufacturing outdoor products, including reloading tools, that have a strong fanbase. According to Lyman, performance means delivering value while advancing technology. Lyman’s products certainly deliver, however, their warranty is not on the par with the other manufacturers described here.
The Pro scale is sturdy and durable. Its base is made from high-impact molded styrene with an extra-large leveling wheel for easy adjustment. It is very precise. It measures to 1/10 of a grain. The capacity of the scale is 500 grains.
Always calibrate the scale on the surface you will be using it on and always have the loading try on the scale. Move the big slider on the left of the beam to zero and the small poise on the right of the beam to zero as well. Check whether the line on the left side of the beam is pointing exactly to the mark on the left tower of the base. If it is not exact, use the screw under the left tower of the base to move it up or down as needed. When it is calibrated, set up the slider and poise to the numbers you want to measure and load the tray up. The scale settles quickly so you will have no problem using it efficiently.
Pros
- Well known brand
- Durable
- Extra-large leveling wheel
- Precise to 1/10 grain
- Maximum capacity of 500 grains
- Easy to calibrate
- Easy to use
- Medium price range
Cons
- Warranty is not as good
Lyman – Brass Smith 500 Metal Reloading Scale
As described above, the Lyman company is renowned for its reloading tools including reloading scales, although its warranty is not the best on the market.
The Brass Smith 500 reloading scale’s body is made from aluminum which reduces vibrations and promotes accuracy. The beam is double-sided and can be used by left- and right-handed reloaders alike. The capacity is 505 grains. The scale is precise to 1/10 grain. It includes magnetic dampening that helps the scale to settle.
Using the scale is easy. Although it comes pre-calibrated from the factory, we recommend calibrating your scale before every use on a new surface and always having the loading tray on. Similarly to its brother, the Pro 500 described above, you just need to move the big slider and the small poise to zero and check if the beam mark is pointing exactly to the mark on the big tower of the base. If not, just use the screw under the big tower to adjust it properly. The calibration is easy to learn. The same applies to the use of this scale. For easier reading of the scale beam, place the scale at eye level.
Pros
- Well known brand
- Sturdy
- Made from aluminum
- Lightweight, only 0.5lbs
- Easy to calibrate
- Easy to use
- Medium price range
Cons
- Warranty is not as good as other companies
RCBS – 502 Reloading Scale
This is another great product from the well-respected company RCBS. As mentioned above, RCBS has been around for over 60 years. It provides good customer service and a limited lifetime warranty.
Its 502 reloading scale is made from cast metal that makes it strong and durable. The capacity is 505 grains. Its accuracy goes to +/- 0.1-grain. There is a magnet inside the big tower on the left of the base that helps the scale to settle faster and be more accurate. It does not hold zero if it is moved around since the plastic knob underneath it levels the scale.
When you first buy your new reloading scale and before every use, you need to calibrate it. It is an easy process thanks to the magnet which keeps the beam inside the big tower on the left side of the base. Place the scale on an even surface, preferably glass. Then you set up the slider and small poise to zero. If the marks on the beam and on the left big base tower don’t match, you can use the plastic knob under the big tower to adjust the level. Always keep the loading tray on the scale when calibrating.
Pros
- Well known company
- Limited lifetime warranty
- Durable metal base
- 505 grain Capacity
- Accuracy to 1/10 grain
- Easy to calibrate
- Easy to use
- Ounce to grain conversion sticker
- Medium price range
Cons
- Does not hold zero when moved
What is a beam scale?
Generally, beam scales use a balance consisting of two platforms connected with a beam. One platform is for the object being weighed and the other is for weights of a known measurement. Users add weights until they equal the weight of the object on the opposite platform, then compute the weight of the object. The beam scale uses gravity and does not need any electricity to function.
Why do you need a reloading scale?
When you are reloading your own cartridges, the basic goal is to make the most accurate ammunition you can. In order to be able to do that, you need to, among other things,
- measure the powder precisely. That is where the reloading scale comes in. Although you can get a powder dispenser that measures the powder by volume, to be truly accurate, those volumes must be checked on a scale.
- Some reloaders even weigh their brass cases and projectiles to get super tight groups.
Beam scales versus digital scales
Both beam and digital scales supply precise measurement of weight. There are many differences between beam scales and digital scales including:
| Beam scale | Digital scale |
| They are accurate and their precision depends on the smallest possible measurement on a given beam scale | They are known to be very precise but prone to inaccuracy |
| Need to be recalibrated after moving them from one surface to another because they are leveled based on the surface they are placed on | Very sensitive to environmental factors that can cause an inaccurate reading. |
| Do not need anything but their mechanical parts to work | Need electricity, usually in form of batteries, to function properly |
| Need to be calibrated mechanically. | Have a button to reset the internal electronics |
| Easy to use once you learn how to use them, the learning curve can be steeper though | Easy to use from the start while the batteries last |
| Do not need to warm up | Need to warm up |
How to choose the best beam scale
There is no “one beam scale fits all” solution to find the best beam scale. What works for one reloader might not work for another one. However, there are general steps to follow when finding the best beam scale for you.
- Always choose a well-known brand as it will guarantee high-quality. Get a warranty so that you can return or exchange the scale if needed.
- Look for a beam scale made from sturdy and durable materials. Such a scale will last you longer.
- Check if the beam is easily readable. Usually, black numbers and marks on a white background or white numbers and marks on a black background are the best choices.
- See how easy it is to calibrate the scale. You will have to zero your scale every time you move it to a new surface to keep it leveled.
- Look at how precise and accurate the beam scale is. Some measure even to 1/20 of a grain. Such a sensitive scale can be harder to learn on.
- The price of a beam scale and your budget will also be important factors, however, we would not recommend sacrificing quality for affordability.
How to use a beam scale
- Place the beam scale on a flat surface, preferably glass.
- Recalibrate your scale. Move all the poises on the beam to zero and see if the mark on the beam is pointing directly to the mark on the side of the scale’s base. Always have the loading pan on the scale when recalibrating.
- If the marks are not pointing directly to each other, use the leveling screw to find zero.
- When the beam scale is calibrated, move the poises to the amounts you want to measure. Fill the loading tray with powder and see if the marks on the beam and the side of the scale’s base are in line. If the beam mark is lower, add powder and vice versa.
Conclusion
- When choosing the perfect beam scale for you, always remember to first consider what the most important characteristics your scale should have are.
- If you are looking for a precise beam scale, choose the Lee Precision scale.
- If you are looking for a big grain capacity, pick RCBS M1000 beam scale.
- If you are looking for a lifetime warranty, go for Redding #2 Master scale.
- If lightweight is the most important aspect, take Lyman Brass Smith 500 scale.
- And if the price is the deciding factor, then you will be happy with Lee Precision scale.
Good luck with choosing your favorite beam scale and with reloading your own ammunition!
