MEC (Mayville Engineering Company) has long been a revered name in the world of shotshell reloading, celebrated for producing robust, dependable, and efficient reloading presses. From the foundational MEC 600 Jr. to the advanced Sizemaster, Steelmaster, and Grabber models, these machines empower enthusiasts to produce custom ammunition tailored to their specific needs. Whether you're loading for trap, skeet, sporting clays, dove hunting, or waterfowl, a MEC reloader provides the control and consistency desired by discerning shooters. Every MEC press is designed to guide shotgun hulls through a series of stations, transforming spent casings into freshly loaded rounds. This intricate process involves decapping (removing the old primer), resizing (restoring the hull's base to original dimensions), priming, powder dropping, wad seating, shot dropping, and finally, crimping. Each stage is crucial, and the integrity of the components performing these functions directly affects the quality and safety of the finished product.The Critical Role of the Knockout Bushing in Shotshell Reloading
So, what exactly is a knockout bushing, and why is it so vital? In your 12-gauge MEC Reloader, the knockout bushing plays a pivotal role in the initial stages of the reloading cycle: decapping and resizing. Located within the reloader's sizing die (or the deprime/resizing station), its primary function is twofold: 1. Decapping: As the spent shotgun hull is pressed into the die, the knockout bushing's internal pin pushes out the spent primer from the primer pocket. A clean and complete decapping action is essential for allowing a new primer to be seated correctly. 2. Resizing: Simultaneously, the bushing contributes to resizing the brass or steel base of the hull. Over time, fired hulls can expand slightly, especially at their base, making them difficult to chamber or cycle properly in a shotgun. The resizing action ensures the hull's base returns to its original, factory-specified dimensions, promoting smooth chambering and reliable extraction in your firearm. Imagine trying to fit an expanded or misshapen hull into your shotgun's chamber – it simply won't work, or worse, it could jam. The knockout bushing, therefore, is directly responsible for the foundational integrity of your reloaded shotshells. Without it performing optimally, the entire reloading process can become frustratingly inefficient, producing unreliable ammunition.Why Your 12-Gauge Reloader Needs a Fresh Knockout Bushing
Like any precision tool, the components of your MEC reloader are subject to wear and tear. The knockout bushing, being integral to the decapping and resizing process, experiences significant stress with every shell processed. Repeated contact with spent primers and hull bases can lead to several forms of degradation: * Worn or Bent Decapping Pin: The thin pin within the bushing can become bent, blunted, or even break over thousands of cycles. This leads to incomplete decapping, leaving old primers lodged in hulls, or making it impossible to seat new ones. * Deformed Bushing Bore: The internal dimensions of the bushing, responsible for guiding the hull and resizing its base, can wear down or become slightly out of round. This results in hulls that are not perfectly resized, leading to tight chambering or extraction issues in your shotgun. * Accumulated Debris: While not strictly wear, powder residue, primer residue, and general grime can build up within the bushing and around the pin, hindering its smooth operation and potentially causing sticking or damage. How do you know if your MEC 12-gauge reloader's knockout bushing needs replacement? Look for these common indicators: * Inconsistent Primer Removal: Spent primers are not always ejecting cleanly, or some remain stubbornly stuck. * Difficulty Seating New Primers: New primers don't seat flush or require excessive force, indicating the primer pocket wasn't fully cleared or the hull base isn't properly resized. * Hulls Not Resizing Properly: Finished shells are tight in your shotgun's chamber, or you notice resistance when loading them into your firearm. This can be a significant safety concern. * Increased Effort During Initial Stroke: You have to apply more force than usual to push the hull through the depriming/resizing station. * Visible Damage: Upon inspection, the decapping pin appears bent, chipped, or the bushing itself shows signs of deformation or excessive wear. If you encounter any of these issues, a replacement for the knockout bushing in your 12Ga MEC Reloader setups (UPC 098489014113, SKU 100832112) is likely the solution. Replacing this single component can revitalize your reloader, restoring its original performance and accuracy.Achieving Flawless Shotgun Ammunition: Benefits of a New Bushing
