Redding Reloading Small-Base Full Length Sizing Die Review

The Story of My Time with the Redding Reloading Small-Base Full Length Sizing Die

For over a decade, I’ve spent more time with gear and equipment than I have with most people, be it deep in the backcountry, tinkering in a workshop, meticulously running experiments in a lab, or out in the unforgiving field. It’s this immersion that lends a certain weight to my observations. When it came time to address a persistent nagging issue with some of my handloads, my sights turned to the Redding Reloading Small-Base Full Length Sizing Die. This wasn’t a casual upgrade; it was a necessary step born from the increasing tightness of modern rifle chambers, especially those found in competition and match-grade firearms. My existing dies, while perfectly adequate for standard chambers, were starting to struggle, leading to inconsistent case neck sizing and, consequently, less-than-ideal accuracy.

The initial impression upon unboxing this particular die was one of understated competence. The Redding Reloading name carries a certain gravitas in the reloading world, and this die certainly felt the part. Machined from heat-treated steel, it possessed a reassuring heft, and the black finish was both practical and aesthetically pleasing. It felt like a tool designed to perform a specific, demanding task and do it well, without unnecessary frills. I’d briefly considered other brands, but the reputation Redding has for precision and durability, especially in their sizing dies, ultimately steered me back to them. My hope was simple: a smooth, consistent sizing operation that would bring my handloads back into tight tolerances.

Real-World Testing: Putting Redding Reloading Small-Base Full Length Sizing Die to the Test

My testing ground for this die was my own reloading bench, a space that sees consistent use across various calibers and bullet weights. The initial setup was straightforward; the die threaded into my press with the expected smooth action, a good sign of quality machining. I began with a batch of .223 Remington brass that had previously been fired in a bolt-action rifle with a known tight chamber. The purpose here was to see if this small-base die could achieve the necessary reduction in case diameter without undue force or strain on the press.

The process was remarkably smooth. Whereas my previous full-length sizing die sometimes required significant leverage, this Redding model moved through the brass with a satisfying, controlled resistance. The case neck reduction was consistent across the entire batch, and more importantly, the shoulder datum was set precisely as I had adjusted it. I encountered no significant issues, no signs of galling or sticking, even after running through dozens of cases consecutively. The die performed its primary function flawlessly from the very first pull of the lever.

Extended use has only solidified my initial positive impressions. Weeks have turned into months, and this Redding die has become my go-to for any brass destined for tighter chambers or semi-automatic platforms where reliable feeding is paramount. I’ve processed hundreds of cases since that initial test run, and the die shows no discernible signs of wear. The heat-treated steel construction and the hand-polished sizing surface seem to live up to their promise of longevity and reduced friction. Cleaning is as simple as wiping it down with a soft cloth and a light application of a bore cleaner or resizing lubricant. There’s no complex maintenance required, just basic care to ensure it continues to operate at its peak performance.

Comparing it to previous experiences, this small-base die stands out. It provides a level of sizing consistency that my older, standard full-length dies simply couldn’t match for these specific applications. While budget dies might get the job done, they often lack the precision and ease of use that this Redding model offers, especially when dealing with challenging brass dimensions. It’s a significant upgrade for anyone serious about precision reloading for specific firearm types.

Breaking Down the Features of Redding Reloading Small-Base Full Length Sizing Die

Specifications

The Redding Reloading Small-Base Full Length Sizing Die is crafted from heat-treated steel, ensuring robustness and durability for countless reloading sessions. Its design is full length, meaning it sizes the entire case, from the neck all the way to the base, which is crucial for ensuring proper chambering and extraction. The sizing diameters are meticulously hand-polished, a feature designed to significantly reduce the effort required for sizing and to prevent brass shavings from accumulating.

These specifications translate directly into practical benefits for the reloader. The heat-treated steel guarantees that the die will withstand the pressures of resizing even the toughest brass without deforming. The hand-polished surface is a key differentiator, leading to a much smoother operation and less wear on both the die and the brass itself, making the reloading process more efficient and less physically demanding. This attention to detail in the manufacturing process is a hallmark of quality reloading equipment.

Performance & Functionality

The primary job of this small-base die is to reduce the diameter of the case body more than a standard full-length die. This is absolutely critical for cartridges fired in firearms with very tight or “worn” chambers, or for cartridges used in semi-automatic actions that require a bit more case clearance for reliable cycling. The Redding Reloading Small-Base Full Length Sizing Die excels in this regard, consistently bringing cases down to the required dimensions. This ensures that reloaded ammunition will chamber reliably and extract smoothly, even in the most demanding firearm configurations.

Its strength lies in its ability to achieve this extra sizing without generating excessive friction or requiring an inordinate amount of force. This means less wear and tear on both the reloader’s press and the brass itself. A potential weakness, though minor, is that for those used to a standard full-length die, the initial setup might require slight adjustments to achieve the desired shoulder setback. However, once dialed in, its performance is exceptional. It meets and often exceeds expectations for those specifically needing its specialized sizing capability.

Design & Ergonomics

The design of this die is purely functional, eschewing any decorative elements for pure utility. The black finish is practical, helping to prevent rust and providing a non-reflective surface. The heat-treated steel construction gives it a solid, professional feel; it doesn’t feel flimsy or cheap in the hand.

Ergonomically, it’s designed to thread into any standard reloading press die head. The knurled section at the top provides adequate grip for initial setup and adjustments. While there aren’t any overtly ergonomic features like padded grips, its design is inherently user-friendly for its intended purpose. The markings on the die are clear and informative, guiding the user through proper installation and adjustment. The smooth, hand-polished interior surface further contributes to usability by minimizing sizing effort.

Durability & Maintenance

Given its heat-treated steel construction and hand-polished internal surfaces, this Redding die is built for longevity. I anticipate it will easily last for tens of thousands of resizing operations, far outliving many other components in a reloading setup. Its robust build means it’s unlikely to crack or warp under normal use.

Maintenance is straightforward and is essentially the same as any other reloading die. A simple wipe-down with a clean cloth after use, perhaps with a very light application of a resizing lubricant or even just a gun oil, is sufficient to keep it in top condition. I make it a habit to lightly oil the threads before storing it to prevent any potential seizing. There are no obvious failure points beyond what might be expected from extremely heavy or abusive use.

Accessories and Customization Options

This product is a single sizing die, and as such, it does not typically come with accessories. It is designed to be part of a larger reloading die set or to be integrated into an existing reloading setup. There are no direct customization options for the die itself, as its function is highly specific and precisely engineered. However, Redding does offer this small-base sizing function in various calibers, allowing reloaders to select the specific die needed for their firearm and ammunition. It is compatible with all standard reloading presses that accept 7/8″-14 thread dies.

Pros and Cons of Redding Reloading Small-Base Full Length Sizing Die

Who Should Buy Redding Reloading Small-Base Full Length Sizing Die?

This die is an absolute must-have for reloaders who frequently work with ammunition intended for competition rifles, match-grade firearms, or any semi-automatic or pump-action rifle that exhibits tight chamber tolerances. If you’ve encountered issues with sticky bolts, difficult chambering, or inconsistent feeding due to brass dimensions that are slightly too large, then this die is your solution. It’s particularly beneficial for those loading for cartridges like the .223 Remington or 5.56 NATO, where variations in chamber size can be pronounced.

However, if you primarily reload for standard bolt-action hunting rifles with generous chambers, or if you are just starting and not yet dealing with specialized firearm requirements, this specific die might be overkill. You might be better served by a standard full-length sizing die initially. For optimal use, a quality reloading press and a digital caliper for precise measurement of case dimensions are highly recommended complementary tools.
