What is H110 and its Properties?
Definition
H110 isn’t just another propellant; it’s a specifically formulated spherical powder often chosen for its power and consistency. It is a double-base powder, meaning it contains both nitrocellulose and nitroglycerin. This combination helps deliver consistent performance, a critical factor when it comes to reloading.
Applications
One of the key characteristics of H110 is its slow burn rate. While this might seem counterintuitive for shotgun shells, especially the smaller 410, the design delivers high pressures over a relatively short period. This characteristic means H110 excels in generating the velocities needed for optimum performance. It is primarily favored in specific shotgun applications and in high-performance handgun cartridges.
Burn Rate
However, its slow burn rate means that H110 is more sensitive to pressure spikes. Improper loads or component selection could lead to dangerous situations. The consistent burn rate is a benefit, but it’s best utilized when coupled with appropriate gun powder measurements to achieve optimal performance.
Considerations
Always make sure that all of your components match what’s listed in the recipe. If you change something, you risk getting different results.
410 Shotgun Overview
Brief History
The 410 shotgun, often lauded for its compact design and ease of use, holds a unique place in the world of firearms. With a legacy spanning over a century, the 410 is smaller in bore size and has an overall reduced size than other shotguns.
Advantages
While compact and manageable, the 410 has certain limitations. Its small payload capacity is a trade-off for its portability. This limits the range and shot count compared to larger gauges.
Disadvantages
Despite its limitations, the 410 finds applications in several fields. It’s a favorite for introducing new shooters to the sport because of its light recoil. It’s used for hunting small game, pest control, and, in some cases, home defense. Understanding its strengths and limitations is important before undertaking any reloading project.

Understanding 410 Load Data Specific to H110
Source of Data
The heart of safe and successful reloading lies in using reliable load data. This data is your roadmap, dictating the quantities and components needed for optimal performance.
Components and Compatibility
Let’s begin with shot size and weight. The choice of shot size is important. Small shot sizes are perfect for target shooting, whilst larger sizes can be used to hunt. The weight of the shot charge impacts pressure, velocity, and pattern. The load data will specify the shot weight the recipe is tested with, which will impact both your pressure levels and overall performance.
Shot Size and Weight
Selecting the right wad is critical. The wad’s function is to provide a gas seal, preventing powder gasses from escaping past the shot column. It also cushions the shot during acceleration, reducing deformation. Using the correct wad that corresponds with the load data is paramount for safety and optimal results. Incorrect wads could lead to excessive pressures or poor shot patterns.
Wads
Primers are also key players. Primers ignite the powder charge. Using the correct primer type, as specified in the load data, is essential. Some powders work better with certain primer types, and using the wrong primer may result in inconsistent ignition or pressure issues.
Primers
Next comes the hull. Different hull types have varying internal volumes and wall thicknesses. This affects pressure and performance. Use the hull type specified in your load data. Some popular choices are Winchester, Remington, and Federal.
Hulls
Finally, proper crimping is vital. Crimping seals the shot shell, keeping the components together and ensuring consistent ignition. Different crimp styles can affect pressure. Always follow the crimp recommendations in your chosen load data.
Crimp
Pressure is another area that must be taken seriously. Never exceed the pressure levels recommended in the load data. Excessive pressures are dangerous. The results could range from a blown-up firearm to serious injury. Always adhere to the data to ensure your safety.
Pressure Levels and Safety
The load data is generally presented in a table. You’ll find columns for various components and results. Understanding the terminology in the table is essential. Expect to find information on: Powder Charge: The weight of H110 in grains, Shot Weight: The weight of the shot charge in ounces or grams, Wad Type: The specific wad model, Primer: The type of primer used, Hull: The hull manufacturer and model, Velocity: The velocity of the shot charge, typically in feet per second (fps), Pressure: The chamber pressure, measured in pounds per square inch (PSI).
Accessing and Interpreting Load Data for the 410
Locating Load Data
The availability of load data is often just a quick internet search away. Hodgdon’s website has a substantial database. Reloading manuals provide a broad range of recipes.

Reloading Process for the 410 using H110 (Step-by-Step Guide)
Safety Precautions
Safety should be your top priority. Always wear safety glasses and hearing protection. Ensure your reloading area is clean and well lit. Reloading should be taken seriously.
Equipment Needed
The equipment you’ll need: Reloading Press: A press designed for shotshell reloading, Powder Scale: For accurate powder measurement, Powder Measure: For consistent powder dispensing, Hull Trimmer (Optional): To ensure consistent hull length, Priming Tool: To seat the primers correctly, Wad Seater: To seat the wad, Shot Dispenser: For measuring shot, Crimp Tool: For crimping the shell.
Steps in Reloading
Start by preparing the hulls. Clean and inspect them for any damage. Resize the hulls, if your press does this.
Then, set the primers. Use the priming tool to seat the primers flush with the base of the hull.
Next, carefully measure the powder. Use a powder measure to dispense the correct amount of H110, based on your load data. Use a powder scale to double-check your powder charge to ensure that your measure is dispensing the correct amount.
Insert the wad. Place the wad into the hull, making sure it’s properly seated.
Now for the shot. Dispense the specified weight of shot. Pour it directly into the wad.
The crimp, properly done, will secure the shot. The crimp should be neat and consistent.
Inspect each loaded round to ensure everything is correct, and then store the ammunition. Ensure ammunition is stored properly in a safe, cool, and dry place.
Troubleshooting Common Reloading Issues
Inconsistent Velocity
Reloading can present challenges. Here’s how to handle some common problems.
Inconsistent velocity can come from many sources. Make sure you’re using the correct powder charge, a suitable wad, and an adequate crimp. Also, consider the consistency of your powder measurements and the quality of your primers.
High Pressure Signs
High-pressure signs are dangerous. If you experience stiff bolt lift, flattened primers, or bulged hulls, stop immediately. Reduce the powder charge. Double-check that you’re using the correct components.
Failure to Fire
Failure to fire? Ensure your primers are seated correctly. Check for debris in the primer pocket. Replace the primer. The hammer could be weak.
Poor Patterns
If you have poor patterns, check the wad. Ensure your shot charge is right.
Safety and Best Practices
Safety should be your primary focus. Here are some critical safety tips: Always wear safety glasses and hearing protection, Reload in a well-ventilated area, Use only the components and quantities specified in the load data, Never exceed recommended load data, Inspect every loaded round carefully, Double-check powder charges and measurements, Keep your reloading equipment clean and well maintained, Start with the minimum load and work your way up, carefully observing for pressure signs.
