The Problem It Solves: Inconsistent Shot Charges

Imagine spending hours at the loading bench, meticulously assembling components, only to find erratic patterns or unpredictable recoil when you finally shoot your reloads. A primary culprit for these inconsistencies is often variations in the shot charge. Even small discrepancies in the amount of shot dropped into each hull can lead to:

• Varying muzzle velocities: Some shells might fly faster, others slower.
• Unpredictable shot patterns: Tight patterns might become open, or vice versa, at different distances.
• Inconsistent recoil: Affecting follow-up shots and shooter comfort.
• Reduced effectiveness in the field or on the range: Missed targets or less effective hunts.

The MEC 502118 Progressive Stage Charge Bar directly addresses these issues by providing a precisely machined cavity designed to consistently drop 1-1/8 ounces of shot with every cycle of your progressive press.

Understanding the Functionality: How a Charge Bar Works

In a progressive shotshell reloader, the charge bar is a sliding component that moves back and forth, transferring a precise amount of powder and shot from their respective hoppers into the shotgun hull. The "progressive stage" aspect means it integrates seamlessly into the multi-station operation of presses like the MEC 650N, MEC 8567N Grabber, or MEC Sizemaster 77 series, among others.

When the reloader handle is actuated:

1. Powder Drop: The powder side of the charge bar aligns with the powder hopper, allowing a measured charge to drop into the hull.
2. Shot Drop: As the handle continues its motion, the shot side of the charge bar aligns with the shot hopper. The 1-1/8 ounce cavity, which was pre-filled with shot during the previous cycle, now empties into the hull.
3. Return Stroke: The bar returns to its original position, ready to be refilled for the next shell.

The accuracy of this shot drop is critical. The MEC 502118 is manufactured with tight tolerances to ensure that the internal volume of its cavity consistently measures out exactly 1-1/8 ounces of lead shot, assuming standard density. For reloaders working with alternative shot materials like steel, bismuth, or various non-toxic alloys, it's crucial to understand that these materials have different densities. A 1-1/8 oz charge bar designed for lead might drop a different weight of steel shot, even if the volume is the same. Always consult a reloading manual for appropriate charge bars and bushings when using non-lead shot.

Key Benefits of the MEC 502118 Charge Bar

Investing in a quality charge bar like the MEC 502118 offers a multitude of advantages that go beyond simply saving money on ammunition:

• Safety Assurance: Consistent charges contribute to safer reloading practices. Knowing that your components are precisely measured minimizes the risk of over-pressure situations from incorrect loads. Always cross-reference with published load data.
• Optimized for Popular Loads: The 1-1/8 ounce shot charge is one of the most widely used and versatile loads for 12-gauge shotshells, suitable for a vast array of shooting applications from trap and skeet to upland game hunting. This charge bar is purpose-built for this popular specification.

Integrating with Your MEC Progressive Press

The MEC 502118 is engineered to be a direct replacement or an additional component for a range of MEC progressive shotshell reloaders. These presses are renowned for their multi-stage operation, allowing reloaders to produce high volumes of ammunition efficiently. Models such as the MEC 650N, MEC 8567N Grabber, MEC 9000GN, and MEC Sizemaster 77 Series often utilize this style of charge bar. Compatibility ensures that the charge bar slides smoothly, integrates with the camming mechanisms, and precisely positions itself for the powder and shot drops. Always refer to your reloader's manual to confirm compatibility and proper installation procedures.

Choosing the Right Components for 1-1/8 oz Loads

While the charge bar handles the shot weight, the overall performance of your 1-1/8 oz load also depends heavily on other components:

• Powder: Different powders have varying burn rates and densities. Always use the specific powder recommended in your reloading manual for a 1-1/8 oz load in your chosen hull and wad combination. The charge bar's powder bushing will need to be selected to dispense the correct weight of that specific powder.
• Wads: Wads play a crucial role in gas sealing, cushioning the shot, and protecting the barrel. There are wads specifically designed for 1-1/8 oz loads, ensuring proper stack height and crimp.
• Hulls: Hulls come in various lengths (e.g., 2-3/4", 3") and base wad designs. Ensure your hull choice is compatible with your desired load.
• Primers: Primers ignite the powder charge. Use the type of primer specified in your load data.
• Shot Type: While the 502118 is calibrated for lead shot, reloaders using steel, bismuth, or other non-toxic shot alternatives must understand that due to differences in density, 1-1/8 oz by volume will equate to a different weight of these materials. For instance, steel shot is less dense than lead, so a 1-1/8 oz volume charge bar will drop a lighter weight of steel. Reloading manuals provide specific data and often recommend different charge bar numbers or adjustments for non-lead shot.

Maintenance and Longevity

To ensure your MEC 502118 Charge Bar continues to deliver consistent performance for years to come, simple maintenance is key:

• Regular Cleaning: Over time, powder residue and shot dust can accumulate. Use a soft brush or cloth to clean the charge bar and its sliding path on the reloader. Avoid harsh solvents that could damage the finish or lubricants.
• Lubrication (Sparing): Some reloaders prefer a very light application of dry lubricant (like graphite or a silicone spray) on the sliding surfaces to ensure smooth operation. Consult your reloader's manual for recommendations.
• Inspection: Periodically inspect the charge bar for any signs of wear, nicks, or burrs that could affect its precision. While MEC products are durable, extreme impact or improper handling could cause damage.
• Proper Storage: Store your charge bar in a clean, dry environment when not in use.
