Winchester switched to bare brass to minimize the required impact force from the hammer or firing pin for reliable ignition. They used to be nickel plated (for corrosion resistance). Note that Winchester has changed the style of these primers.

Winchester primers are packaged in packs of 100, or bricks of 1000 (a box of 10 packs of 100). Winchester makes great reloading components, and primers are no exception.
– No dedicated large pistol magnum primer from Winchester. – Compact trays that allow primer pickup tubes to be used directly. – Dual purpose primer, no need to empty priming system between magnum/standard load changes within the same primer size. These primers have always worked really well for me with zero malfunctions. I’ve used both the old style (nickel plated) and the new style (bare brass). I have personally loaded thousands of 45 acp, 44 special, and 44 magnum loads with these primers. None the less, Winchester categorizes these primers as “for standard or magnum loads”. These primers are a bit more powerful than typical large pistol primers, but not as powerful as standard magnum primers. In this review, we’ll take a look at Winchester’s dual purpose large pistol primers (WLP).
