The .45 Colt cartridge, a venerable round with a rich history, continues to be a favorite among handgun enthusiasts. Its versatility, from mild target loads to potent hunting rounds, makes it a rewarding cartridge to reload. However, safety is paramount when working with any firearm, and reloading is no exception. This guide provides comprehensive 45 Colt load data, but it's crucial to remember this information is for educational purposes only and should not be considered a substitute for your own research and adherence to safety guidelines. Always consult your reloading manual and meticulously follow its instructions.
Understanding 45 Colt Load Data Variables
Before delving into specific load data, understanding the key variables influencing your reloading process is critical. These variables interact to determine the pressure and velocity of your rounds, directly impacting their safety and performance.
1. Powder Type and Charge:
The type and amount of powder significantly influence the round's performance. Different powders burn at different rates, and even small variations in powder charge can drastically alter pressure. Never substitute powders without consulting a reliable reloading manual specifically for your chosen powder.
2. Bullet Weight:
Heavier bullets generally require higher powder charges to achieve similar velocities compared to lighter bullets. Matching the bullet weight to the appropriate powder charge is vital for safe and consistent results.
3. Case Capacity:
Different manufacturers produce cases with slightly varying capacities. Using a case-sizing die is essential for maintaining consistent case dimensions and ensuring uniform powder charges. Overfilling a case can lead to dangerously high pressures.
4. Primer Type:
While the primer's impact on pressure is less significant than other factors, using the correct primer type is important for reliable ignition. Consult your reloading manual for the recommended primer type for your specific powder and bullet combination.
Sample 45 Colt Load Data (For Educational Purposes Only)
The following data represents a small sampling of possible loads and is provided solely for illustrative purposes. Do not use this data without cross-referencing it with your specific reloading manual for your chosen components. Variations in components and equipment can drastically affect results.

| Bullet Weight (grains) | Powder Type | Powder Charge (grains) | Primer Type | COL (inches) | Notes |
|---|---|---|---|---|---|
| 250 | Unique | 7.0 | CCI 350 | 1.200 | Mild target load |
| 250 | Unique | 8.0 | CCI 350 | 1.200 | Moderate target load |
| 255 | Power Pistol | 6.0 | CCI 350 | 1.205 | Medium velocity load |
| 300 | Trail Boss | 10.0 | CCI 350 | 1.250 | Heavy bullet, lower velocity |
Understanding the Table:
- Bullet Weight (grains): The weight of the bullet in grains.
- Powder Type: The type of gunpowder used.
- Powder Charge (grains): The weight of the powder charge in grains.
- Primer Type: The type of primer used.
- COL (inches): Cartridge Overall Length (COL) in inches, which is the total length of the loaded cartridge.
- Notes: Any specific observations or intended use of the load.
Safety Precautions:
- Always wear safety glasses and hearing protection.
- Work in a well-ventilated area.
- Double-check your measurements at every step.
- Never exceed the maximum recommended load in your manual.
- Start with a lower charge and gradually work up to your desired velocity, meticulously monitoring pressure signs.
- Regularly inspect your equipment for any signs of wear or damage.
- Dispose of any defective components immediately.
Further Research and Resources:
To ensure safe and accurate reloading, consult reputable reloading manuals from manufacturers like Hodgdon, Alliant, and IMR. These manuals contain comprehensive data for various powders and bullet combinations. Always prioritize safety and thorough research when working with firearms and reloading.
This article provides a starting point for understanding 45 Colt load data. Remember, responsible reloading requires careful planning, attention to detail, and a commitment to safety. Always consult multiple sources and never deviate from established guidelines. Happy and safe reloading!
