Introduction
The .308 Winchester, a cartridge celebrated for its versatility and accuracy, has solidified its place as a favorite among hunters, target shooters, and military personnel worldwide. Its popularity stems from a balanced combination of power, manageable recoil, and widespread availability of components. Finding the right combination of powder, primer, and bullet is crucial to unlocking the full potential of this exceptional cartridge. Among the many powder options available, Varget consistently shines as a top choice for those seeking exceptional performance. This article delves into the world of Varget load data 308, providing you with the knowledge and insights needed to safely and effectively reload for your .308 Winchester rifle. We’ll explore the properties of Varget, its benefits, and, most importantly, the specific load data you need to craft accurate and powerful ammunition. Reloading requires careful attention to detail and adherence to safety protocols, which are paramount throughout this process.
Understanding the Core of Varget Powder
Varget, manufactured by Hodgdon Powder Company, is a single-base, extruded propellant meticulously designed for accuracy and consistency. Its formulation is optimized for use in cartridges with a moderate to large case capacity, making it an ideal match for the .308 Winchester. The extruded nature of the powder means it is composed of small cylindrical grains, which allows for more consistent metering and predictable burn rates. This, in turn, translates to better accuracy and shot-to-shot consistency on the range or in the field.
The burning characteristics of Varget are considered relatively slow-burning for the .308 Winchester. This makes it well-suited for pushing heavier bullets, maximizing velocity, and maintaining a flatter trajectory. Furthermore, Varget boasts excellent temperature stability, a critical advantage for shooters who encounter a wide range of environmental conditions. The consistent performance across various temperatures contributes to predictable ballistics and reduces the need for frequent adjustments to your point of impact. These benefits are a significant reason why so many reloaders turn to this powder for their .308 Winchester rifles.
Varget’s ability to provide consistent results is also attributed to its deterrent coating, which slows the initial burn and prevents pressure spikes. This design leads to smoother pressure curves and further contributes to accuracy and consistent performance. The powder’s versatility extends to its compatibility with various bullet weights, allowing you to tailor your loads for specific shooting purposes. From hunting to long-range target shooting, Varget provides the flexibility to achieve superior results.
Prioritizing Safety in Every Step
Reloading ammunition can be an extremely rewarding hobby, but it demands unwavering attention to safety. Before embarking on the journey of reloading, you must recognize the inherent risks involved. Incorrect procedures, faulty components, and exceeding established load data can lead to serious injury or damage to your firearm. The information provided in this article is for informational purposes only, and it should not be considered a substitute for proper training and adherence to safe reloading practices.
Always wear appropriate safety equipment when reloading. This includes eye protection (safety glasses or goggles) and hearing protection. Work in a well-ventilated area to minimize exposure to powder fumes. The use of a reloading manual from a reputable source, such as Hodgdon or a major bullet manufacturer, is *essential*. These manuals provide specific load data, including recommended powder charges, bullet types, primer types, and other crucial information. *Never* deviate from these guidelines.
Always begin by using the minimum recommended load. Gradually increase the powder charge, following the reloading manual’s instructions, while carefully monitoring for any signs of excessive pressure. Observe your brass cases for signs like flattened primers, hard bolt lift, or cratering around the firing pin. These are all indicators of excessive pressure and warrant immediate cessation of your reloading process. If any of these symptoms are observed, stop reloading immediately and consult a qualified gunsmith. Always prioritize the safe handling and storage of reloading components.
Load Data for Select Bullet Weights
Before diving into load data, remember that this is just a starting point. Always cross-reference the following information with current and reliable reloading manuals. These manuals offer the most up-to-date and precise information. The data presented below is for informational purposes only, and you should always use it as a reference and start low and work up your load gradually and safely.
Bullet Weight: One Hundred Fifty Grains:

Influencing Factors on Load Behavior
Several factors influence the performance of your reloaded ammunition. Understanding these variables is critical to achieving consistent accuracy and maintaining safety.
Barrel Length
A longer barrel allows for a more complete powder burn, resulting in higher velocities. Conversely, shorter barrels may result in lower velocities.
Case Capacity
The internal volume of your cases can vary slightly from brand to brand and even within the same brand. Larger case capacity will typically allow for a slightly greater powder charge.
Bullet Seating Depth
The depth to which you seat the bullet affects the internal volume of the case and the pressure curve. Small adjustments in seating depth can impact accuracy.
Ambient Temperature
Temperature changes can significantly impact powder performance. Varget, although known for its temperature stability, can still be affected by extreme temperature shifts.
Altitude
Altitude affects air density and therefore bullet trajectory. Higher altitudes will result in less air resistance and changes in your bullet’s performance.
Component Variations
Differences between primer brands, case brands, and even different lots of powder can influence the load’s performance. Testing is crucial.
Refining Your Reloading Process
Achieving the desired accuracy and consistency requires a refined reloading process. Here are some tips to help you.
Thorough Case Preparation
Case preparation is essential to ensure uniform and consistent results. Clean your cases thoroughly to remove any debris. Trim the case length to ensure uniformity, and chamfer and deburr the case mouths for optimal bullet seating.
Precise Powder Measurement
Accurate powder measurement is perhaps the single most important factor influencing reloading consistency. Use a quality powder scale and carefully weigh each powder charge. Use a powder trickler for fine adjustments.
Consistent Bullet Seating
Consistent bullet seating depth ensures uniform internal case volume. Use a high-quality seating die and follow its instructions carefully.
Developing an Accurate Load
Developing an accurate load is an iterative process. Begin with the starting load and progressively increase the powder charge, while closely monitoring for any signs of excessive pressure. Test different powder charges and seating depths to find the combination that delivers the best results for your rifle.
