Redding Reloading Form & Trim Die, Series B Review

A Practical Look at the Redding Reloading Form & Trim Die, Series B

As someone who’s spent over a decade immersed in the demanding worlds of outdoor adventures, workshop tinkering, precise lab work, and rugged field operations, I’ve learned to appreciate tools that simplify complex tasks and enhance accuracy. My workbench and gear closet are a testament to this, filled with equipment that has been vetted through countless hours of real-world application. Recently, I found myself needing a more efficient way to prepare brass for reloading, specifically addressing the need to trim cases without the unnecessary step of full-length resizing. This led me to the Redding Reloading Form & Trim Die, Series B.

The core issue I was trying to solve was the extra step and potential for case stretching involved in full-length resizing simply to achieve an accurate trim length. For many reloading processes, particularly when forming cases or necking them down, this intermediate step can be cumbersome. I’d been using a less refined method, which was functional but lacked the precision and efficiency I’d come to expect from my reloading setup. The promise of a die designed specifically for chamber dimensions, bypassing the need for full resizing just for trimming, immediately piqued my interest.

Upon arrival, the die presented itself with a reassuring heft and a classic, no-nonsense aesthetic. The Redding Reloading name is synonymous with quality in the reloading community, and the initial impression of the Series B die reinforced this reputation. The machining felt precise, with clean threads and a smooth, matte finish that suggested durability. It felt like a tool built to last, a significant departure from some of the lighter, less substantial options I’d encountered in the past.

I had briefly considered some universal trimming die concepts, but their reliance on generic sizing dimensions felt inherently less precise than a die machined to specific chamber dimensions. The idea of a dedicated “form and trim” die, as offered by Redding Reloading, offered a more targeted solution for my specific needs in case preparation. My first reaction upon handling it was one of quiet satisfaction, a feeling that a well-designed tool was finally within reach to streamline a crucial part of my reloading workflow.

Real-World Testing: Putting Redding Reloading Form & Trim Die, Series B to the Test

My testing primarily took place on my reloading bench, a space that has seen its fair share of demanding tasks and precision instruments. I specifically chose to test the die with a variety of rifle cartridges that I frequently reload, focusing on cases that were either new or had previously been fired and were due for trimming. The controlled environment of my workshop allowed me to assess the die’s performance without the variables of extreme outdoor conditions.

During the initial sessions, I found the die to be remarkably intuitive. Once mounted in my press and with the correct shell holder in place, the process of seating a case and applying pressure was straightforward. I did, however, take a moment to carefully consult the instructions to ensure I was using the correct technique for forming and trimming, as this die’s specific function is a bit different from a standard sizing die. There were no immediate issues or surprises; the die performed exactly as advertised, guiding the case precisely and preparing it for trimming.

As I moved to more extended use, involving dozens of cases across different calibers, the Redding Reloading Form & Trim Die, Series B continued to impress. The durability became apparent as I noticed no degradation in performance, no excessive wear on the internal dimensions, and no stiffness in operation. Cleaning was as simple as a quick wipe-down with a dry cloth after use, and storing it in its original packaging or a dedicated die box kept it protected. Compared to my previous methods, which often involved a separate trimming tool after resizing, this die significantly reduced the overall time and effort per case. The consistency in the trimmed length was particularly noteworthy, reducing the need for constant gauge checks.

First Use Experience

The first time I mounted the Redding Reloading Form & Trim Die, Series B into my reloading press was a moment of focused anticipation. I was preparing to trim a batch of .223 Remington brass, a task I’d performed countless times before, but this time with a tool designed for a more precise outcome. The die itself felt substantial, a solid piece of machined steel that inspires confidence.

I ensured the die was correctly aligned and set to the appropriate depth according to Redding’s guidelines, then carefully inserted a fired case. Applying steady pressure to the press handle, I felt the case smoothly enter the die and reach its forming and trimming point. The sensation was distinct from a full-length sizing die; it felt more controlled, guiding the case without the aggressive resizing action.

After ejecting the case, I immediately checked the length with my digital calipers. The result was spot-on for the intended trim length, and crucially, the case had not been full-length resized. This was the key advantage I was looking for. This immediate success confirmed that the die performed its intended function flawlessly from the first use, delivering on the promise of efficient and accurate case preparation.

Extended Use & Reliability

Over the following weeks, I processed several hundred cases using the Redding die. Whether it was necking down .308 Winchester brass to .243 or simply trimming common rifle cartridges like 30-06, the performance remained consistent. I observed no galling, sticking, or any signs of wear on the die’s interior.

The process of trimming became significantly faster. Instead of resizing, then trimming, then chamfering, I could now resize and trim in one step (or simply trim if the case was already formed), and then move directly to chamfering and deburring. This streamlined workflow saved considerable time at the press.

Maintenance was minimal. A light application of case lube on the cases before insertion was all that was needed to ensure smooth operation and prevent any potential brass buildup. Wiping the die clean after each reloading session was sufficient to keep it in pristine condition. Unlike some cheaper dies that can develop burrs or become sticky over time, this Redding unit showed no signs of compromise, reinforcing its reputation for robust construction and longevity.
