Buying Guide:

Before you take a decisions to purchase a case trimmer, the first thing you should verify is that if the case trimmer meets your needs perfectly.

There’re five types of case trimmers.

1. Raw Speed(On Press Trimming)
2. Simplicity and Low Cost
3. Lathe type
4. High-Volume Precision
5. Low-Volume Precision(Shoulder-indexing)

Now, let’s know the criteria,

Shell Holder

Shell Holders are something that is used to hold the shells while trimming. Basically, these holders are responsible for keeping the case stable at its place. However, different sizes are available according to the sizes of calibers.

Now it’s your decision to choose the right case trimmer with a shell holder that meets your need. A serious reloader should not skip this feature while selecting a case trimmer.

Ease of Use

Obviously, usability is the most important factor that one should consider while choosing a case trimmer. In the usage part, one should consider these three things: simple to use, efficiency at work, and quality result.

However, you should consider a product that can be mounted easily with good stability. After all, if you consider using a portable case trimmer, so never forget to check the weight and durability.

Speed

Being a gun enthusiast speed should be the primary priority for reloading. If you are a regular reader, then you should go for a case trimmer that can do your job in lesser time.

No doubt, the sooner you will trim, the more you will reload bullets. So, never overlook this feature while considering a case trimmer.

Durability

Durability should be considered as it will keep you away from hectic repair schedules for your trimmer. You should consider a trimmer with sturdy body metal that could handle your workload.

Likewise, choose it according to the quantity of trimming you need to do. Better the durability, higher is the chance to take the workload.

Chamfering and Deburring

Chamfering and Deburring are the stages after case trimming, where the case undergoes the smoothing process. Well, this process is necessary because it removes the sharp edges of the bullet giving it a perfect shape for the next use.

You should consider this feature because many case trimmers come with a preinstalled chamfering and deburring tool. And for some trimmers, you need to purchase it separately. Eventually, you should go with the former one to be on a safer side.

Polishers and Tumblers

Not a mandatory but an advantage if the case trimmer has a built-in polisher or tumbler. They can be used to polish the bullets as well as the gun. The polishers increase the life span of the cartridges by removing the debris(left near the mouth) down to the internal chamber.

FAQs

1. Do you need to trim pistol brass?

No, you don’t need to trim the pistol brass. It’s because normally the brass shrinks after several firings. So, trimming is not necessary.

2. Are Bullets Poisonous?

Yes, bullets contain lead, which makes it poisonous from the time of manufacture.

3. Which Case Are Trimmers The Best?

The case trimmers that match your needs are the best among all for you. However, trimmers from Lyman, Hornady, Frankford Arsenal etc. are some of the trusted brands.

4. How does a case trimmer work?

After you shoot a bullet, the cartridge left gets elongated due to the gunfire pressure. This elongated brass makes the cartridge unfit to go inside a reloading press. However, you resize it to the perfect shape by conditioning them with a case trimmer.

That’s the basic operation.

I must say it is easy to use a case trimmer. However, it goes with several steps, such as:

• In the first step, the case trimmer should be placed on a reloading bench and secured firmly with C-clamps.
• Now the job starts, where you need to the adjustable collet and put correct pilots and put it in the case trimmer.
• Then after inserting the case inside the sizing die, adjust the position of the cutter teeth with the case for a perfect cut.
• Make some trail cuts to check the length adjustments. Replace the case with a caliper to check it.
• Make fine adjustments and lock it with a stop collar.
• Readjust if needed
• Finally, you can now trim the case cautiously.

For more information, you can always check the instructions manual provided by the manufacturers.
