Introduction to RCBS 357 Carbide Dies
RCBS 357 carbide dies are essential tools for handloading enthusiasts and high-volume shooters who want to reload their .357 Magnum and .38 Special ammunition. These precision-engineered dies are designed to deliver superior performance, easy adjustment, and smooth operation, whether you're reloading 10 or 10,000 cartridges a year.
Understanding the RCBS 357 Carbide Die Set
The RCBS 357 carbide die set typically includes three essential components:
1. Carbide Sizing Die
2. Expander Die
3. Bullet Seating Die
Each of these dies plays a crucial role in the reloading process, ensuring that your handloaded ammunition is consistent, accurate, and safe to use.
Carbide Sizing Die
The carbide sizing die is the first step in the reloading process. It resizes the fired brass case to its original dimensions, ensuring proper fit in your firearm's chamber. The carbide construction of this die eliminates the need for case lubrication, making the reloading process faster and cleaner.
Expander Die
The expander die slightly enlarges the case mouth to the proper diameter for accepting a new bullet. This step is crucial for ensuring smooth bullet seating and preventing damage to the bullet during the seating process.
Bullet Seating Die
The bullet seating die is responsible for seating the new bullet to the correct depth in the case. Proper bullet seating is essential for accuracy and safety. Many RCBS 357 carbide die sets also include a built-in crimping feature in the seating die, which secures the bullet in place and ensures reliable feeding in semi-automatic firearms.
The Reloading Process with RCBS 357 Carbide Dies
Now that we understand the components of the RCBS 357 carbide die set, let's walk through the reloading process step by step.
Step 1: Case Preparation
Before using your RCBS 357 carbide dies, you need to prepare your brass cases. This involves inspecting them for defects, cleaning them, and trimming them to the correct length if necessary.
Step 2: Resizing and Decapping
Insert the prepared case into the carbide sizing die. As you operate the press, the die will resize the case to its original dimensions and remove the spent primer. Thanks to the carbide construction, you don't need to lubricate the cases for this step.
Step 3: Priming
After resizing, install a new primer in the case. This can be done using a separate priming tool or a priming system integrated into your reloading press.
Step 4: Powder Charging
Using a powder measure or scale, carefully dispense the appropriate amount of powder into the primed case. Always follow published load data and never exceed maximum recommended charges.
Step 5: Expanding the Case Mouth
Use the expander die to slightly flare the case mouth. This step makes it easier to seat the bullet without damaging its base.
Step 6: Bullet Seating
Place a bullet on top of the charged case and use the seating die to press it into the case to the correct depth. If your die includes a crimping feature, this will also be applied during this step.
Step 7: Final Inspection
Carefully inspect your completed rounds for any defects or inconsistencies before using them.
Tips for Using RCBS 357 Carbide Dies
To get the most out of your RCBS 357 carbide dies, consider the following tips:
1. Always follow the manufacturer's instructions for die setup and adjustment.
2. Keep your dies clean and lightly oiled to prevent rust and ensure smooth operation.
3. Check your die settings periodically to ensure consistency in your reloaded ammunition.
4. Use a case gauge to verify that your resized cases meet proper specifications.
5. When reloading .38 Special cases, use the included spacer ring with your RCBS 357 carbide dies to accommodate the shorter case length.
