RCBS 90366 Trim Pro-2 Manual Case Trimmer with Shield .22-.45 Cal

Unparalleled Accuracy and Safety in Ammunition Reloading with the RCBS 90366 Trim Pro-2

When striving for unparalleled accuracy and safety in ammunition reloading, one fundamental step often overlooked by beginners, but rigorously practiced by seasoned handloaders, is case trimming. As brass cases are fired and resized, they stretch, growing longer with each cycle. If left untrimmed, these cases can become too long, potentially leading to dangerous pressure spikes, difficult chambering, or even damage to your firearm. This is precisely the critical problem that dedicated tools like the RCBS 90366 Trim Pro-2 Manual Case Trimmer with Shield are designed to solve.

Why is Case Trimming Absolutely Essential for Every Handloader?

For anyone involved in the meticulous art of reloading, whether for competitive shooting, precision hunting, or just enjoying the craft, understanding the importance of case length consistency is paramount.

• Ensuring Safety: The most critical reason to trim cases is safety. An overly long case can crimp the bullet into the rifling upon chambering. This "bullet jam" significantly increases chamber pressure when the round is fired, leading to potentially catastrophic failures like ruptured cases, damaged firearms, or even serious injury to the shooter. The RCBS Trim Pro-2 helps maintain safe cartridge dimensions, preventing these hazardous situations.
• Achieving Optimal Accuracy and Consistency: Precision shooters know that consistency is key. Variations in case length can affect bullet seating depth, neck tension, and ultimately, muzzle velocity and shot-to-shot consistency. By trimming every case to a uniform, specified length, the RCBS Trim Pro-2 ensures that each round performs predictably, contributing to tighter groups and improved downrange performance. This is particularly vital for disciplines where every millisecond and every millimeter counts.
• Preventing Damage to Your Firearm: Long cases can also interfere with the smooth operation of your firearm's action, especially in semi-automatic rifles. They might not chamber or extract correctly, leading to frustrating malfunctions. Furthermore, the constant rubbing of an untrimmed case neck against the chamber's leade can cause premature wear to your barrel, reducing its lifespan and accuracy potential.
• Extending Case Life: While it might seem counterintuitive, properly trimming cases can actually extend their overall lifespan. By removing the stretched material, you are conditioning the brass, making it more uniform and potentially reducing stress points that could lead to cracks or splits in the future.

Introducing the RCBS Trim Pro-2 Manual Case Trimmer: Your Gateway to Precision Reloading

The RCBS Trim Pro-2 Manual Case Trimmer is a robust, reliable tool engineered to bring precision and consistency to your reloading bench. Designed by RCBS, a name synonymous with quality and innovation in the reloading community for decades, this trimmer simplifies the often-daunting task of case preparation. It’s a foundational piece of equipment for anyone serious about handloading precise and safe ammunition, whether you’re working with rifle or pistol cartridges.

Understanding the Core Features and Benefits:

The RCBS Trim Pro-2 isn't just a simple cutting tool; it's a thoughtfully designed system that offers distinct advantages for the discerning reloader:

1. Manual Operation for Unmatched Control: Unlike power trimmers, the manual operation of the Trim Pro-2 provides the reloader with a direct, tactile feel for the cutting process. This allows for precise control over the trimming operation, ensuring that you cut just the right amount of brass to achieve the exact specified case length. This hands-on approach is highly valued by reloaders who prioritize meticulous attention to detail and prefer to 'feel' the process. It's particularly beneficial when working with small batches or highly critical loads.
2. Integrated Trimming Shield for Enhanced Safety and Cleanliness: A standout feature of the RCBS Trim Pro-2 is its integrated trimming shield. This transparent shield serves a dual purpose:
   • Safety: It acts as a barrier, deflecting brass shavings and chips away from your eyes and face, significantly reducing the risk of injury during the trimming process. This is a crucial safety enhancement that shows RCBS's commitment to user well-being.
   • Cleanliness: The shield helps contain the fine brass dust and shavings, keeping your reloading area cleaner and reducing the spread of metallic particles, which can be a nuisance and a potential health concern if inhaled.
3. Wide Caliber Compatibility (.22-.45 Cal): The Trim Pro-2 is designed for versatility, accommodating a broad spectrum of popular cartridges, from small .22 caliber cases all the way up to large .45 caliber cases. This wide range makes it an incredibly cost-effective investment, as it can be used for a diverse collection of firearms and ammunition needs without requiring multiple specialized tools. It’s perfect for the reloader who works with various rifle and pistol calibers.
4. Durable, High-Quality Construction: RCBS is renowned for its commitment to building reloading equipment that lasts a lifetime. The Trim Pro-2 is no exception, featuring robust materials and a sturdy design that can withstand years of rigorous use on the reloading bench. Its heavy-duty construction ensures stability during operation, contributing to consistent and precise trims every time.
5. Easy and Intuitive Setup: While precision is its hallmark, the Trim Pro-2 is surprisingly straightforward to set up and operate. Once mounted to your reloading bench, adjusting for different case lengths and calibers is a simple process, allowing reloaders to quickly transition between different cartridges.

• The Cost-Conscious Reloader: Investing in quality tools that perform consistently and last a long time ultimately saves money. The Trim Pro-2 is a one-time investment that will serve your reloading needs for decades, reducing the need for constant replacements or upgrades.

How Do I Achieve Consistent Case Length with My RCBS Trim Pro-2? A Step-by-Step Guide

Using the RCBS Trim Pro-2 effectively is a straightforward process once you understand the steps involved. This fundamental operation is crucial for creating accurate and safe ammunition.

1. Mounting the Trimmer: Securely mount your RCBS Trim Pro-2 to a sturdy workbench using the pre-drilled holes in its base. Stability is key for consistent results.
2. Selecting the Right Shell Holder and Pilot: The Trim Pro-2 uses standard shell holders and pilots (sold separately at DEGuns). You will need the correct shell holder to firmly hold your specific case caliber and the appropriate pilot to guide the cutting tool inside the case neck. Ensure both are clean and free of debris.
3. Inserting the Case: Place the appropriate shell holder into the trimmer’s collet. Then, insert a resized brass case into the shell holder. The case should fit snugly.
4. Setting the Trim Length: The Trim Pro-2 features a micrometer-style adjustment for setting the desired case length. Consult your reloading manual for the "trim-to" length for your specific cartridge. Loosen the locking screw on the adjustment knob, rotate the knob to set the cutter to the precise length, then tighten the locking screw. This ensures all subsequent cases are trimmed to the exact same dimension.
5. Trimming the Case: With the case firmly seated and the trim length set, gently turn the large handle on the trimmer. The cutter will shave off excess brass from the case mouth until it reaches the pre-set length. Apply steady, even pressure. The integrated shield will help contain the brass shavings.
6. Inspecting and Deburring/Chamfering: Once trimmed, remove the case. The case mouth will likely have a burr (a sharp edge) on both the inside and outside. Use a chamfering and deburring tool (also available at DEGuns) to smooth these edges. Chamfering the inside of the case mouth helps with bullet seating, while deburring the outside prevents damage to the bullet and aids in smooth chambering.
7. Repeat: Continue this process for all your cases, periodically checking the trim length with a caliper to ensure consistency, especially when changing calibers or after trimming a large batch.

What Accessories Do I Need with My RCBS Trim Pro-2?

While the RCBS Trim Pro-2 is a complete trimming unit, certain essential accessories are sold separately but are absolutely necessary for its operation and for completing the case preparation process. When you source your reloading supplies from a trusted vendor like DEGuns, you'll find everything you need:

• RCBS Shell Holders: You will need the specific shell holder that matches the base of the cartridge you are trimming. RCBS offers a wide range of shell holders to accommodate almost any cartridge.
• RCBS Trimming Pilots: These small, caliber-specific inserts fit into the case mouth and guide the cutter, ensuring concentric and straight cuts. You'll need a pilot for each caliber you intend to trim.
• Case Gauges or Calipers: To accurately measure the trim length before, during, and after the trimming process, a high-quality case gauge or a precise digital/dial caliper is indispensable.
• Chamfer/Deburr Tool: After trimming, every case mouth will have sharp edges. A chamfering tool bevels the inside of the case mouth, making bullet seating easier, and a deburring tool removes the sharp edge from the outside, preventing damage to the bullet and ensuring smooth chambering.
• Case Lube: For some resizing operations, case lube is essential to prevent cases from sticking in the die. While not directly for trimming, it's part of the overall case preparation process that often precedes trimming.
