  • Understanding the Risks: Be aware of potential dangers, including:
    • Overpressure: Exceeding the maximum safe pressure for the cartridge can cause catastrophic firearm failure.
    • Incorrect Powder Charges: Too little powder can lead to inconsistent performance; too much can create dangerous pressures.
    • Primer Malfunctions: Primers can misfire or detonate unexpectedly.
    • Equipment Failure: Reloading tools can break or malfunction.

Never deviate from the published load data without a thorough understanding of the potential consequences. When in doubt, err on the side of caution.

Essential Components for .22-250 Reloading

Reloading a .22-250 cartridge involves several key components that must be carefully selected and prepared. The quality of these components significantly impacts the accuracy and performance of the final product.

Brass Cases

Brass cases are the foundation of your ammunition.

Case Selection

You can reload new or once-fired cases. The source of the brass impacts quality, and new brass tends to be more uniform. Popular brands include Winchester, Lapua, and Remington. Inspect cases for any signs of damage, such as cracks, dents, or bulges.

Case Preparation

This is a critical step in ensuring consistency and accuracy.

Cleaning

Cleaning the brass removes dirt, carbon, and other contaminants. Methods include tumbling, using a sonic cleaner, or simply wiping them down.

Sizing

Sizing restores the case dimensions to factory specifications, ensuring proper chambering in your rifle. Full-length sizing resizes the entire case, while neck sizing only resizes the neck. The best choice depends on your rifle and intended use.

Trimming

Trimming ensures the cases are all the same length, which improves consistency. Use a case trimmer and measure the trimmed cases to maintain consistent lengths.

Chamfering and Deburring

These steps remove any sharp edges from the case mouth, making it easier to seat the bullet and preventing damage.

Primer Pocket Cleaning and Uniforming

This ensures consistent primer seating and ignition.

Primers

Primers initiate the ignition of the powder.

Primer Types

Small rifle primers are used in the .22-250. Different brands and types of primers exist (e.g., standard, magnum). Magnum primers are sometimes used with slower-burning powders or in colder weather.

Primer Selection

Match the primer to the powder type and the overall purpose of your load. Refer to your reloading manual for specific recommendations.

Powders

The powder is the propellant that generates the energy to propel the bullet.

Powder Types

Various powders are suitable for the .22-250, each with a different burn rate. Some popular choices include IMR 4064, Varget, H380, and Reloder 15. The choice of powder influences velocity, pressure, and accuracy.

Powder Selection Criteria

Choose a powder based on the desired velocity, accuracy, and temperature sensitivity. Temperature-stable powders offer more consistent performance across a range of temperatures. Consult reloading manuals and experiment to find what works best in your rifle.

Powder Measuring

Accurately measuring the powder charge is critical. Use a powder measure to dispense consistent charges. This can be done manually with a volumetric powder measure or electronically with an auto-trickler system. Weigh each charge on a precision scale to ensure accuracy.

Bullets

The bullet is the projectile that is fired from the rifle.

Bullet Weight Selection

The twist rate of your rifle’s barrel determines the range of bullet weights it can stabilize. Heavier bullets generally offer better ballistic coefficients and downrange performance, but your rifle must have the correct twist rate to stabilize them.

Bullet Types

Various bullet types are available, including varmint bullets (designed for rapid expansion), match bullets (designed for extreme accuracy), and hunting bullets (designed for controlled expansion and penetration). Choose the bullet type based on your intended purpose.

Bullet Brands and Recommendations

Popular brands include Sierra, Hornady, Nosler, and Berger. Explore different bullet profiles and weights to find the best match for your rifle.

.22-250 Reloading Data: A Starting Point for Your Reloads

This is a vital section of reloading, providing the foundational information for safe and effective loads. *Always* consult at least two reputable reloading manuals and compare their data before loading any rounds. The data provided here is meant to be a starting point. Always begin loading at the lowest charge listed, and carefully observe your brass, primer condition, and any other pressure signs as you gradually increase the powder charge. *Never* exceed the maximum charge.

This data is indicative and should be tested in *your specific* rifle. The performance you achieve might vary depending on your rifle’s barrel, components, and environmental conditions.

Remember, the goal is not to reach the highest possible velocity, but to find the load that produces the tightest groups with excellent accuracy.

*(Note: Because of the inherent variability in reloading and legal considerations, I cannot provide specific load data. *Instead*, here’s how the data would be organized and what information is essential. The actual numbers, powder types, and bullet weights would need to be looked up in a published reloading manual. Use the following as a guide to understanding how to read and use load data, then consult reputable sources.)*

Organized Load Data Example

Here’s how a table might look, showing the information you’d find in a reloading manual.

Powder Type Bullet Weight (gr) Primer Type Case Type Charge Range (gr) Velocity (fps) (Approx.) Notes
IMR 4064 50 Small Rifle Winchester 30.0 – 33.0 3500 – 3800 Begin at 30.0gr, check for pressure signs.
Varget 50 Small Rifle Winchester 31.0 – 34.0 3450 – 3750 Accuracy may improve at lower charges.
H380 55 Small Rifle Remington 35.0 – 37.5 3400 – 3700 This powder can be temperature sensitive; watch for pressure changes.
Reloder 15 55 Small Rifle Remington 32.0 – 35.0 3300 – 3650 Good accuracy potential.
  • Powder Type: The specific brand and type of powder (e.g., IMR 4064).
  • Bullet Weight (gr): The weight of the bullet in grains (e.g., 50gr).
