Finding out exactly how many 9mm brass cases you get per pound isn't as simple as looking up a single number. The weight varies depending on several factors, impacting your reloading budget and planning. This guide delves into the specifics, providing you with the information you need to accurately estimate your 9mm brass yield.
Factors Affecting 9mm Brass Weight Per Pound
Several factors influence the number of 9mm brass cases you'll find in a pound:
-
Manufacturer: Different manufacturers use slightly varying amounts of brass in their casing production. This subtle difference in thickness and overall dimensions can impact the weight. You might find a noticeable difference between cases from Federal, Winchester, or Remington, for example.
-
Case Condition: The condition of the brass plays a significant role. Clean, un-tarnished cases will weigh slightly more than those that are dirty, corroded, or have been heavily fired. Cleaning and prepping your brass before weighing will provide a more accurate count.
-
Type of Brass: While most 9mm brass is made from standard alloys, subtle variations in the composition can affect the final weight.
-
Measurement Method: Weighing methods also influence results. Using a precise scale will provide more accurate results than a less calibrated device.
Estimating 9mm Brass Cases Per Pound: A Practical Approach
While a precise number is elusive, a generally accepted estimate places the number of 9mm brass cases per pound between 60 and 70. However, this is just an average. You might find fewer or slightly more depending on the factors mentioned above.
To get a more accurate measure for your specific brass, consider these steps:
-
Weigh a Sample: Weigh a batch of 10-20 cleaned 9mm cases using a calibrated scale. Record the weight.
-
Calculate the Average: Divide the total weight by the number of cases to find the average weight per case.
-
Estimate the Total: Divide 16 ounces (1 pound) by the average weight per case. This will give you a much more accurate estimate of how many cases are in a pound of your specific brass.
Optimizing Your Reloading: Beyond the Weight
While knowing the weight is crucial for budgeting and purchasing, it's only one piece of the reloading puzzle. Consider these additional factors for efficient reloading:
-
Brass Sorting: Sorting your brass by manufacturer and condition helps ensure consistency in your reloads.
-
Case Preparation: Thorough cleaning, inspecting, and sizing are essential steps to ensure reliable reloads.
-
Component Sourcing: Consider the cost and availability of primers, powder, and bullets in addition to the brass itself.
Conclusion: Accuracy Through Measurement
There's no magic number for 9mm brass per pound. The best approach is to weigh your own brass to determine the precise amount you'll receive per pound, taking into account the factors affecting weight. This ensures accurate reloading calculations and cost estimation. By understanding the variables and performing your own measurements, you'll gain a far clearer and more accurate picture of your 9mm brass yield.
