Let’s Talk About Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass
The Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass represents a cornerstone for reloaders seeking precision and consistency in their ammunition. Winchester, a name synonymous with American firearms history, offers this unprimed brass for shooters who demand control over every aspect of their reloading process. This brass allows the handloader to build custom loads tailored to their specific rifle and shooting needs, optimizing for accuracy and performance.
I’ve been handloading for over a decade, primarily for hunting rifles chambered in various magnum calibers, and the quest for consistent and reliable brass is never-ending. Factory ammunition often provides excellent performance, but I value the control and customization that handloading offers, particularly when chasing that perfect sub-MOA group. Winchester brass has always been a reliable choice for me, and I was keen to explore the potential of their 7mm WSM offering for a custom lightweight hunting rifle build.
Upon receiving the Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass, the first thing I noticed was the clean, uniform appearance of the cases. The brass was free of dings and dents, with consistent dimensions that spoke to Winchester’s quality control. The weight of the brass felt substantial, indicating a good wall thickness, and the overall impression was one of quality and durability.
Compared to other brands of 7mm WSM brass I’ve used in the past, such as Nosler and Remington, the Winchester brass seemed to offer a balance between hardness and malleability. Some brass is too brittle, leading to cracking during resizing, while others are too soft, resulting in excessive expansion and reduced case life. Winchester brass typically avoids these extremes. I chose the Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass because of Winchester’s reputation for producing reliable brass that performs well across a wide range of reloading applications.
My initial reaction was excitement, tempered by the knowledge that the real test would come at the reloading bench and on the range. The prospect of building custom loads with this high-quality brass and tailoring them to my specific rifle was certainly enticing.
Real-World Testing: Putting Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass to the Test
First Use Experience
I initially tested the Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass at my reloading bench and subsequently at my local outdoor shooting range. The temperature was around 70 degrees Fahrenheit with a slight breeze, providing ideal conditions for load development. I used a Forster Co-Ax press, Redding dies, and a variety of powders and bullets to develop several different loads.
The brass resized smoothly with minimal effort, and the primer pockets were consistently sized and uniform. The case mouths were also uniform and required minimal trimming after the initial sizing. I experimented with different powder charges and bullet seating depths to find the optimal load for my rifle. The Winchester brass consistently produced tight groups, with some loads achieving sub-MOA accuracy.
There were no major issues encountered during the initial loading process, although I did notice that the flash holes required deburring on a few cases. This is a common occurrence with unprimed brass, and it’s easily remedied with a deburring tool.
Extended Use & Reliability
After several weeks of consistent use, the Winchester 7mm Winchester Short Magnum Unprimed Rifle Brass has proven to be extremely reliable and durable. I have reloaded some of the cases up to five times with no signs of cracking or excessive expansion. The primer pockets remain tight, and the brass continues to resize smoothly.
The Winchester brass has held up exceptionally well to the pressures of the 7mm WSM cartridge. There are no signs of excessive wear and tear, and I expect to get many more reloadings out of these cases. The brass cleans easily with a tumbler and stainless steel media, maintaining its original luster and appearance. Compared to some other brands of brass I’ve used in the past, the Winchester brass exhibits superior consistency and longevity. It definitely outperforms some of the cheaper, imported brass I’ve experimented with.
