Understanding the Power Within: Introducing BLC-2
Reloading ammunition is a rewarding pursuit that allows shooters to tailor their rounds to their specific firearms and shooting needs. However, it demands a strong understanding of components, safety, and meticulous attention to detail. One of the key elements in achieving successful and safe reloading is selecting the right propellant. Among the many options available, BLC-2 powder, manufactured by Hodgdon, stands out as a versatile choice, particularly for certain rifle calibers. This article serves as a comprehensive guide to understanding, using, and finding reliable BLC-2 powder load data to maximize your reloading efforts.
BLC-2, a spherical powder produced by Hodgdon Powder Company, has earned a reputation for its versatility and performance. It’s known for its ease of metering, a crucial factor for consistent powder charges, which directly impacts accuracy. The spherical shape allows the powder to flow smoothly through the powder measure, leading to more uniform results. It’s a double-base powder, meaning it utilizes both nitrocellulose and nitroglycerin. This composition helps it achieve its burning characteristics, which are often described as being in the medium-burn-rate range, although slightly faster than some other popular powders. This characteristic makes BLC-2 well-suited for various rifle cartridges where a moderate burn rate is desirable.
Beyond its inherent characteristics, BLC-2’s appeal lies in its ability to deliver solid performance in several popular rifle calibers. Its versatility makes it a go-to choice for reloaders looking for reliable results. It often yields good accuracy potential, provided appropriate loads are used. The spherical nature of the powder also allows for high case fill percentages, which can contribute to more consistent ignition. However, like all powders, BLC-2 has its limitations. Reloaders should always be aware of its sensitivity to temperature changes. Fluctuations in temperature can influence pressure and velocity, requiring adjustments to loads to maintain optimal performance in varying environmental conditions.
Safety First: The Cardinal Rules of Reloading
The most critical aspect of reloading is safety. It’s a process that demands unwavering adherence to established procedures and a profound respect for the potential energy involved. Ignoring safety protocols can lead to serious injury or damage to firearms. Prior to embarking on a reloading journey, you should make certain that you have the necessary knowledge, equipment, and workspace.
Essential safety equipment is non-negotiable. Eye protection, in the form of safety glasses or goggles, is mandatory at all times. Cases can rupture, primers can fail, and debris can fly during the reloading process. Gloves, especially when handling primers and powder, are recommended. Adequate ventilation is another key element. Powder fumes can be hazardous, so a well-ventilated reloading area is crucial to prevent the buildup of harmful gases.
The storage of powder and primed cases also requires care. Keep powders in their original containers, away from heat, sparks, and direct sunlight. Primers are extremely sensitive and should be stored separately from powders in a cool, dry place. Always handle all reloading components with care. Make it a habit to keep the loading area clean and organized.
Recognizing the warning signs of excessive pressure is critical. These can include flattened primers, cratering (a small crater around the firing pin indentation), ejector marks on the case head, and difficult bolt lift. Should you observe any of these, immediately cease firing and examine your reloads. Reduce the powder charge by a reasonable amount and retry, continuing to monitor for any sign of excess pressure. If the issue persists, consider consulting a reloading manual or experienced reloader for additional advice. Never reload cartridges that exhibit signs of excessive pressure or damage.
Finding Trustworthy Information to Guide Your Reloading
Accurate and reliable load data is the cornerstone of safe and effective reloading. Never, ever experiment with load data, particularly without clear guidance. Reliance on incorrect or unverified information is one of the most common causes of reloading mishaps. Your goal should be to always verify your loads.
The most authoritative source for load data is the powder manufacturer. Websites like Hodgdon’s website (www.hodgdonreloading.com) typically provide comprehensive load data for their products. Always check the website of the manufacturer to determine the newest available information.
Reloading manuals from respected publishers, such as Hornady, Sierra, Speer, and Lyman, are also indispensable. These manuals offer meticulously tested load data, including the bullet weight, powder charge ranges, primer recommendations, and cartridge overall length (COAL). They often include ballistic information, such as velocity.
Bullet manufacturers, such as Sierra, Barnes, and Nosler, often publish load data for their products, too. If you are reloading a specific bullet from these makers, always consult their resources for precise data.
Understanding the Language of Load Data
Load data charts can appear complicated, but they are relatively easy to decipher. The data typically includes:
- Bullet Weight: This specifies the weight of the bullet in grains.
- Powder: The specific powder used (in this case, BLC-2)
- Primer: The recommended primer type. Primer selection can subtly influence performance.
- Powder Charge Range: This specifies the minimum and maximum powder charges in grains. Always start with the minimum load and work your way up, observing for pressure signs.
- Cartridge Overall Length (COAL): COAL is the total length of the loaded cartridge. Accurate COAL is essential for safe and consistent performance.
- Velocity: The muzzle velocity (in feet per second) that can be expected with a particular load. (Note that velocity data is often developed in specific test barrels, so results can vary depending on the firearm.)
Remember, load data is often specific to certain components. If you deviate from the components specified in the load data (e.g., use a different primer), you may need to adjust your loads.
Popular Calibers and Their BLC-2 Powder Profiles
Now let’s consider some specific examples, keeping in mind that this information is for guidance only and should always be verified with multiple sources.
The .223 Remington:
This immensely popular cartridge thrives with BLC-2. Here is some example load data for illustrative purposes, remembering to always start low and watch for pressure signs:
- Bullet Weight: 55 grain
- Powder Charge Range: A range might be 25.0-27.0 grains. Begin at the lower end!
- Primer: Small rifle primer
- COAL: Approximately 2.200 inches
- Note: Velocities will vary according to barrel length and other factors.
- Bullet Weight: 62 grain
- Powder Charge Range: A range might be 23.5 – 26.0 grains. Always begin with a low charge.

The Core Reloading Process
Reloading can be broken down into steps, each critical for safety and good results.
- Case Preparation: This includes cleaning the cases, trimming them to the correct length, and sizing them. Sizing ensures the case dimensions are correct for your firearm.
- Priming: Insert a new primer into the primer pocket.
- Powder Charging: Carefully measure the correct amount of BLC-2 powder. Consistent powder charges are essential. BLC-2 meters well in most powder measures, but ensure your measure is dispensing the desired charge consistently.
- Bullet Seating: Seat the bullet to the correct COAL. Proper seating ensures proper chambering and safe operation.
- Inspection: Thoroughly inspect each loaded round to ensure the process was completed correctly. Check for proper bullet seating depth, case dimensions, and any visible defects.
Troubleshooting Challenges and Difficulties
Reloading is not always perfect. Here are common issues.
Excessive pressure presents itself in many forms. Flattened primers, cratering, ejector marks, and difficult bolt lift are all signs of excess pressure. If any of these are noted, reduce the powder charge. Overpressure can damage the firearm and injure the shooter.
Accuracy problems can sometimes be addressed by adjusting the powder charge, although other issues may arise. Experiment with different bullet seating depths, or if that does not work, consider other factors.
While BLC-2 generally meters well, variations in charge can occur. If metering inconsistencies arise, check your powder measure and ensure it is functioning correctly. A consistent flow is essential for accuracy.
Inconsistent velocities can stem from various causes. Examine your loading process. Is your technique consistent? Is your powder charge measured precisely? Are your components of good quality? If problems persist, evaluate all components.
