Are you wondering what a case calibrator is and why it is so important in the world of ammunition reloading? Simply put, it is a tool that restores cases to their original shape and dimensions after firing. This allows us to reuse the case, saving money and having more control over the quality of our ammunition.
Case Calibrator – What Is It?
A case calibrator is a device used to restore cartridge cases to the correct dimensions after they have been fired from a weapon. During firing, the case expands under the pressure of propellant gases, conforming to the chamber. After removing the case from the weapon, its dimensions may deviate from the standard, making it impossible to reuse in ammunition reloading. And that's where the calibrator comes in.
Ammunition reloading is the process of re-preparing cartridges, which allows shooters to adjust the parameters of the ammunition to their needs and preferences. Case calibration is one of the key stages of reloading because it ensures that the case will fit into the weapon's chamber and will be safe to use. Without calibration, reloading would be risky, and the ammunition might not work properly.
Why is Case Calibration So Important?
You might think: "Why bother with calibration when you can buy new ammunition?". Yes, you can. But reloading, and in particular case calibration, offers several specific benefits:
- Cost Savings: Reloading allows you to significantly reduce the cost of ammunition, especially in larger quantities.
- Adaptation to the Weapon: The ability to precisely match the ammunition to a specific weapon, which translates into better accuracy and repeatability.
- Satisfaction: For many shooters, reloading is a hobby and a way to deepen their knowledge of ammunition and ballistics.
Imagine you have an AR15 rifle that loves a specific combination of bullet and powder. With reloading, you can consistently produce ammunition with the same parameters, which guarantees repeatable results on the range.
Types of Case Calibrators
There are various types of calibrators available on the market, differing in design and purpose. The most popular ones are:
- Die Calibrators: Used in reloading presses, they provide precise and repeatable calibration.
- Handheld Calibrators: Smaller and more portable, ideal for calibration in the field or in situations where you do not have access to a reloading press.
- Universal Calibrators: Can calibrate cases of different calibers, which is convenient for those who reload ammunition in multiple calibers.
The choice of the right calibrator depends on your needs and budget. If you are just starting your adventure with reloading, a die calibrator will be a good choice. If you need something more mobile, consider a handheld calibrator.
.How to Use a Case Calibrator? Step by Step
The case calibration process is relatively simple but requires adherence to certain safety rules. Here are the steps to follow:
- Clean the Cases: Before calibration, the cases should be thoroughly cleaned of dirt, fouling, and other contaminants. This can be done using an ultrasonic tumbler or manually.
- Lubricate the Cases: Lubricating the cases with a special preparation facilitates the calibration process and prevents the case from getting stuck in the calibrator.
- Place the Case in the Calibrator: According to the calibrator manufacturer's instructions.
- Perform the Calibration: Using a reloading press or manually, depending on the type of calibrator.
- Remove the Lubricant: After calibration, the lubricant should be removed from the cases with a special preparation or cloth.
Remember that safety is paramount. Always wear safety glasses and gloves when reloading ammunition. And be sure to read the calibrator's instruction manual before using it.
What to Look for When Choosing a Calibrator?
When choosing a case calibrator, it is worth paying attention to several key factors:
- Caliber: Make sure the calibrator is suitable for the caliber of ammunition you are reloading.
- Material: Choose a calibrator made of high-quality materials, such as hardened steel, which will ensure durability and reliability.
- Precision: Check reviews from other shooters and make sure the calibrator provides precise calibration.
- Price: Calibrators can cost from a few dozen to several hundred dollars. Choose one that fits your budget.
Case Calibration and Safety
Safety during ammunition reloading is a priority. An incorrectly calibrated case can lead to dangerous situations, such as:
- Cartridge Jam in the Chamber: Which may make it difficult or impossible to fire.
- Weapon Damage: In extreme cases, an improperly calibrated case can damage the chamber or other parts of the weapon.
- Dangerous Shot: Improper propellant combustion can cause an uncontrolled increase in pressure and potentially lead to an explosion.
Therefore, it is so important to use high-quality calibrators and follow all safety rules when reloading ammunition. If you have any doubts, consult an experienced reloader.
Summary
A case calibrator is an essential tool for anyone who is serious about reloading ammunition. It allows you to save costs, adapt the ammunition to the weapon, and achieve better results on the range. Remember, however, that safety is paramount and always follow all rules during reloading.
Frequently Asked Questions
Can I use the same calibrator for different calibers?
No, calibrators are usually designed for specific calibers. Using a calibrator of the wrong caliber can damage the case or the calibrator itself.
How often should I calibrate cases?
Cases should be calibrated after each firing to restore them to the correct dimensions and ensure safe reuse.
Is case calibration difficult?
Case calibration is not difficult, but it requires precision and following instructions. With the right equipment and a little practice, anyone can learn to calibrate cases.
What lubricants are best for case calibration?
There are special lubricants for case calibration on the market that facilitate the process and prevent the case from getting stuck in the calibrator. Choose a lubricant from a reputable company that is designed for this purpose.
Where can I buy a good case calibrator?
Case calibrators can be purchased in gun and shooting accessories stores, online stores, and from distributors of ammunition reloading equipment.
Is it worth investing in a more expensive calibrator?
Investing in a more expensive calibrator may be worthwhile if you are reloading large quantities of ammunition or you need very high precision. More expensive calibrators are usually made of better materials and provide greater durability and reliability.
Does case calibration affect the accuracy of ammunition?
Yes, case calibration affects the accuracy of ammunition. A properly calibrated case ensures a better fit into the chamber and more repeatable propellant combustion, which translates into better accuracy.
Can I calibrate cases without a reloading press?
Yes, there are handheld calibrators that can be used without a reloading press. They are ideal for calibration in the field or in situations where you do not have access to a press.
