Understanding Accurate Magpro Powder
Knowing your components is crucial for successful and safe reloading. Understanding Accurate Magpro, its properties, and its ideal applications is the foundation for achieving optimal results.
Accurate Magpro is a double-base, extruded propellant. The “double-base” designation indicates that it contains both nitrocellulose and nitroglycerin, which work together to produce a powerful and consistent burn. The extruded form means the powder is shaped into small, cylindrical grains. Compared to some other popular powders, Magpro falls into a mid-range burn rate category. This balanced burn rate makes it particularly suitable for a wide variety of rifle cartridges.
This powder’s versatility shines through in its ability to produce impressive velocities while maintaining a relatively moderate pressure curve. It’s a good choice for larger rifle cartridges, but the specifics are always reliant on the bullet weight and the particular load data. Its design also makes it capable of delivering good performance in several popular cartridges.
The advantages of using Accurate Magpro extend beyond sheer performance. Reloaders often find Magpro offers a consistent burn, contributing to better shot-to-shot consistency and improved accuracy. This consistency translates into tighter groupings downrange. Furthermore, the powder is known to meter quite well through powder dispensers, allowing for repeatable and accurate powder charges.
However, the advantages are always paired with the critical need for safety. Never, ever deviate from published *Accurate Magpro load data*. Always start with the minimum recommended load and work your way up, watching carefully for pressure signs. Powder is a propellant, and when misused can be dangerous. Always store your powder in a cool, dry place, away from direct sunlight and any sources of ignition. Handling should be done with care, and safety glasses should always be worn.
Finding and Using Accurate Magpro Load Data
Reliable *Accurate Magpro load data* is the cornerstone of safe and effective reloading. It dictates the amount of powder, the type of primer, the specific bullet, and the overall cartridge length needed for optimal performance. The data must be followed carefully, and the sources must be reputable.
One of the most reliable sources is the Accurate Powder website. Here, you’ll find detailed load data for various cartridges, often updated with new bullet and powder combinations. The website usually contains very specific information, directly from the manufacturer.
Reloading manuals are another invaluable resource. Manuals published by reputable companies provide comprehensive load data for a wide array of cartridges, often including information about different bullet weights, primer types, and case manufacturers. They are regularly updated, reflecting the ongoing development in the field of reloading and ballistics. Familiar names like Lyman, Hornady, Speer and others have long been trusted sources.
Online forums and communities can offer additional information. However, always approach online data with caution. Verify any load data with at least one other reliable source before using it. Cross-referencing information is critical.
Decoding load data charts is essential. You’ll encounter several key pieces of information in these charts. The most important are the bullet weight, the type of bullet, the type of primer recommended, the brand of case, the overall cartridge length (COL), and the powder charge range. The charts will indicate the starting load and the maximum load, and the data should always be followed in that order.
The start with the minimum load is a golden rule. This provides a margin of safety. You gradually increase the powder charge in small increments, while carefully observing your reloads for signs of excessive pressure.
Recognizing pressure signs is paramount. Excessive pressure can lead to dangerous situations. Watch for flattened primers, which may have a distinctly smooth appearance. Examine the spent case for ejector marks (the imprint of the ejector on the case head) and look for any bulging or swelling in the case head.
