The Good
The Bad



Finding the best reloading powder scale is no small task with the immense diversity of models on the market today. There are actually quite a few precision scales that allow you to measure accurate amounts of powder so you can fully customize your ammo. Here are a few things you might want to take into account before buying your first reloading scale.

Ensure precise measurements with an accurate scale

If you want to get a good reloading powder scale, then precision should be the first characteristic you should look at. Depending on the particular types of ammo you need to reload, you might need to weigh tiny amounts of powder so getting a model that’s accurate down to 0.1 grains can be extremely useful.

By getting highly accurate measurements, you can obtain good results every time while also ensuring that the cartridges or shotgun shells have the desired properties. You can also measure just the right amount of powder for particular charges so you can hunt different types of game with the same rifle.

If precision is extremely important, then so is capacity. For smaller workloads, a 500-grain scale might be enough so you don’t have to spend more money on an expensive model. However, if you want faster load times, especially if using one of the fast presses, then you might require a higher-capacity scale that’s able to measure up to 1000 grains or even more.


Ease of use and durability

While you might want to get a cheap mechanical powder scale, you also need to take ease of use into consideration. You can definitely find some affordable models out there, yet you might want a scale that’s easy to operate so you don’t sacrifice speed and comfort for just a few bucks’ worth of savings.

If you’re left-handed or think that you might not be the only person using the scale, then you might want to consider getting an ambidextrous model. The good news is that there are actually quite a few scales that are just as easy to operate with the left hand as with the right.

Whether you’re a passionate hunter or just a hobbyist who enjoys going to the firing range from time to time, you’d be better off investing in a durable model. This usually implies that the body is made of die-cast metal, with a tray that’s made of aluminum or another metal that’s resistant to corrosion. A damping mechanism is also great for lowering maintenance needs.


Don’t forget about other handloading equipment

When looking at powder scales for sale, you might also want to consider getting one of the starter kits. While you could very well get a press, powder measure, priming tool, and other equipment pieces separately, you could save quite a bit of money by getting the full package in one go.

Fortunately, there are quite a few kits on the market that are suited for both beginners and professionals. For the price of a couple of hundred dollars or so you can purchase an entire set that gives you all the tools you need to start reloading shotshell hulls and cartridges of varying gauges. Some packages even include a manual which is excellent for amateurs.
