Designed by RCBS, a name synonymous with reloading excellence for over 75 years, this set provides the essential tools for transforming spent brass into highly accurate, reliable, and consistent ammunition, allowing you to maximize your rifle's potential and your shooting experience.

Why Choose Full Length Sizing for the .30-378 Weatherby Magnum?

The .30-378 Weatherby Magnum is a high-pressure, high-velocity cartridge known for its formidable recoil and impressive ballistics. When such a cartridge is fired, the brass case expands to fit the rifle's chamber. While neck sizing can be adequate for cases repeatedly fired in the same rifle, full length sizing is often critical for several reasons:

• Universal Compatibility: If you intend to use your reloaded ammunition in different .30-378 Weatherby Magnum rifles, or if you ever share your handloads, full length sizing ensures the cases are returned to their original, factory-specified dimensions. This guarantees reliable chambering and extraction in any compatible firearm, preventing frustrating stoppages or misfeeds.
• Reliable Function in All Firearms: While the .30-378 Wby Mag is primarily a bolt-action cartridge, any deviation from factory dimensions can still lead to difficult chambering, especially in rifles with tighter chambers or if brass has been fired multiple times. Full length sizing resolves this by completely resetting the case.
• Maintaining Consistent Headspace: Over time, brass can stretch, and if not properly resized, this can lead to excessive headspace, which is a significant safety concern and can also impact accuracy. The full length sizing die pushes the shoulder back, restoring proper headspace and ensuring a safe and consistent fit in the chamber.
• Enhanced Case Life (with proper lubrication): While some argue that full length sizing "works" the brass more, proper lubrication and careful adjustment minimize this effect. The critical benefit is that by returning the case to spec, you reduce stress on the action and improve the overall reliability of your ammunition.

For high-performance cartridges like the .30-378 Wby Mag, where precision and reliability are paramount, a full length sizing die set is often the preferred choice for serious reloaders.

Understanding the RCBS 29501 Full Length Die Set Components

This RCBS die set is a meticulously crafted, two-die system, engineered to provide everything you need for the fundamental steps of reloading your .30-378 Weatherby Magnum brass:

1. Full Length Sizing/Decapping Die: This is the workhorse of the set. Its primary function is to resize the fired brass case back to its original factory dimensions, ensuring it will chamber reliably in any rifle chambered for the .30-378 Weatherby Magnum. During this process, the integral expander-decapping unit simultaneously removes the spent primer from the primer pocket and slightly expands the case neck to the correct diameter, preparing it for a new bullet. RCBS's dies are known for their precision-machined internal surfaces, which minimize brass galling and ensure smooth operation. The vented design prevents pressure buildup that can occur during sizing.
2. Bullet Seating Die: Once the case is sized, primed, and charged with powder, the bullet seating die is used to precisely seat the bullet into the case neck to the desired overall cartridge length (OAL). This die features a robust design that ensures the bullet is seated straight and concentric to the case, which is absolutely critical for achieving optimal accuracy. The bullet seating stem is designed to cradle the bullet, preventing deformation or damage during the seating process. For the .30-378 Weatherby Magnum, achieving the correct OAL is vital for consistent chamber pressure and feeding in your rifle's magazine.

Both dies are constructed from hardened steel, ensuring exceptional durability and a long service life, even with the repetitive stresses of reloading thousands of cartridges. They also feature RCBS's signature Sure-Lock rings, which provide positive locking to maintain your die settings once adjusted, eliminating the need for constant recalibration.

How This RCBS Die Set Solves Common Reloading Challenges

Reloading can seem daunting at first, but with the right tools, it becomes a rewarding endeavor. The RCBS 29501 Full Length Die Set addresses several common challenges faced by reloaders:

• Inconsistent Ammunition: By precisely resizing cases and seating bullets, this set helps eliminate variations in your handloads that lead to fliers and inconsistent groups. The precision of RCBS dies means each cartridge you produce will be remarkably similar to the last.
• Difficulty Chambering: Cases that are not properly resized can be extremely difficult to chamber, potentially causing dangerous situations or ruining a hunting opportunity. Full length sizing ensures your ammunition slides effortlessly into the chamber every time.
• Shortened Case Life: While full length sizing does work the brass, RCBS dies are designed with smooth internal finishes and proper tolerances that minimize excessive brass stretching or fatigue when used with proper lubrication. This helps prolong the life of your expensive .30-378 Weatherby Magnum brass.
• Primer Crushing/Misfires: The integrated decapping pin is robust and precisely positioned, making decapping spent primers simple and reliable without damaging the primer pocket.
• Bullet Deformation: The bullet seating die's design cradles the bullet, preventing concentricity issues or damage to the bullet's ogive, which is crucial for ballistic performance and accuracy, especially with long, heavy .30-caliber bullets often used in the .30-378 Wby Mag.

Real-World Applications and User Outcomes

For the Precision Shooter:
If your goal is to achieve sub-MOA (Minute of Angle) groups at 1000 yards or beyond with your .30-378 Weatherby Magnum, consistent ammunition is paramount. This die set provides the foundation for creating ammunition with minimal runout and consistent bullet seating depth, two critical factors for long-range accuracy. Users consistently report tighter groups and more predictable ballistics when using RCBS dies for their precision reloading.

For the Big Game Hunter:
Imagine you've drawn a coveted tag for elk, moose, or dangerous game, and your shot needs to count. The last thing you want is a round that won't chamber or a load that doesn't perform as expected. This die set helps you create highly reliable and consistent hunting ammunition, ensuring your .30-378 Weatherby Magnum delivers devastating performance exactly when you need it most. Many hunters rely on handloads crafted with RCBS dies for the utmost confidence in the field.

For the Cost-Conscious Handloader:
Ammunition for the .30-378 Weatherby Magnum can be prohibitively expensive. Reloading with this RCBS die set significantly reduces your per-round cost, allowing you to shoot more, practice more, and experiment with different bullet and powder combinations without breaking the bank. The initial investment in reloading equipment quickly pays for itself, especially with high-volume or specialized cartridges.

How to get started with your RCBS Full Length Die Set:

1. Clean and Inspect Brass: Before sizing, ensure your fired .30-378 Weatherby Magnum cases are clean and free of debris. Inspect for cracks or other damage.
2. Lubricate Cases: This is crucial for full length sizing. Apply a thin, even coat of high-quality case lubricant (like RCBS Case Lube-2 or Imperial Sizing Wax) to the entire case body, just below the shoulder. Do not over-lubricate.
3. Adjust Sizing Die: Install the full length sizing die into your reloading press. Raise the ram to the top of its stroke, then screw the die down until it just touches the shell holder. Lower the ram, then screw the die down an additional 1/8 to 1/4 turn to ensure a full sizing stroke. Lock it in place with the Sure-Lock ring.
4. Size and Decap: Place a lubricated case onto the shell holder and raise the ram firmly into the die. You'll feel resistance as the case is sized and the primer is decapped. Lower the ram, and your case should now be resized and decapped.
5. Clean Primer Pockets and Trim (if necessary): After sizing, clean the primer pocket. Measure the case length; if it exceeds the maximum safe length for the .30-378 Weatherby Magnum, trim it back to spec. Chamfer and deburr the case mouth.
6. Prime Cases: Using your preferred priming tool, seat a new primer into the primer pocket.
7. Powder Charge: Use a precise powder measure and scale to dispense the correct, safe charge of powder according to your reloading manual.
8. Adjust Seating Die: Install the bullet seating die. Place a charged, primed case with a bullet on top into the shell holder. Raise the ram until the case and bullet enter the die. Screw down the seating stem until it just touches the bullet. Lower the ram. Incrementally adjust the seating stem and seat test bullets until you achieve your desired Overall Cartridge Length (OAL). Lock the die in place.
9. Seat Bullets: Seat the remaining bullets, periodically checking OAL to ensure consistency.
