Step-by-Step Reloading Guide 📖

📌 Step 1. Inspect the Brass: Before reloading, inspect each casing for signs of damage or excessive wear. Discard any damaged or questionable brass.

📌 Step 2. Resize and Decap: Use a reliable resizing die to resize the brass back to the correct dimensions. Remove the spent primer during this step.

📌 Step 3. Clean the Brass: Thoroughly clean the resized brass to remove dirt, debris, and any residue from the resizing process. Ultrasonic cleaners and tumblers are popular options for achieving sparkling clean brass.

📌 Step 4. Priming: Insert new primers into the primer pockets of the cleaned and resized brass using a reliable priming tool. Ensure consistent and proper primer seating.

📌 Step 5. Powder Charging: Use a quality powder scale and measure the desired amount of powder for each casing. Consistency and precision are crucial in this step to maintain accuracy and safety.

📌 Step 6. Bullet Seating: Carefully seat the desired bullet into the case mouth using a proper seating die. Pay attention to proper alignment and seating depth.

📌 Step 7. Crimping (Optional): Depending on your specific needs and preferences, you may choose to apply a crimp to ensure bullet retention. Not all reloaders opt for crimping, so it’s essential to research and make an informed decision.

📌 Step 8. Final Inspection: Once you’ve completed the reloading process, perform a final inspection of each round, checking for proper primer seating, overall cartridge length, and other critical factors.

Can I mix brass from different manufacturers when reloading 300 WSM?

Mixing brass from different manufacturers is possible, but it’s important to consider a few factors and approach it with caution. Here’s what you need to know:

  • 🔀 Brass Compatibility: While the dimensions and overall specifications of 300 WSM brass are standardized, there may still be slight variations between different manufacturers. Mixing brass from different sources can result in variations in case capacity, wall thickness, and overall dimensions. These variations may impact cartridge performance, consistency, and accuracy.
  • 🔄 Load Development: When using mixed brass, it’s crucial to perform load development and testing. Start with conservative loads and gradually work your way up, monitoring performance, accuracy, and pressure signs. Carefully observe any differences in velocities and groupings to determine the suitability of the mixed brass.
  • 🔀 Uniformity and Consistency: To ensure optimal results, strive for uniformity and consistency in your reloading process. This includes factors such as case trimming, case neck tension, and primer seating depth. Consistency across different brands of brass helps promote reliable performance and accuracy.
  • 🧩 Sorting and Preparation: Before reloading, sort your brass based on brand and visually inspect each casing for signs of damage or excessive wear. Removing any questionable brass from the mix ensures safer and more reliable reloading results.
  • 🔀 Considerations for Precision Shooting: If you’re engaged in precision shooting or seeking the utmost consistency, it’s generally recommended to stick with brass from a single manufacturer. This minimizes potential variations and streamlines your reloading process.
How To Clean The Brass?

🚿 Step 1: Gather Your Dirty Brass. Collect your dirty brass casings and remove any debris, dirt, or spent primers that may be present. Give them a quick once-over with a magnet to remove any steel or iron contaminants that may have found their way into the mix.

🧽 Step 2: Choose Your Cleaning Method. There are various methods to clean brass, so choose the one that suits your preferences and resources. Here are a couple of popular options:

  1. Tumbling: Prepare your brass for a refreshing spin! Use a tumbler along with cleaning media, such as crushed walnut shells or stainless steel pins. Add your brass and let the tumbler work its magic, agitating and scrubbing away dirt and grime.
  2. Ultrasonic Cleaning: Give your brass a luxurious ultrasonic bath! Ultrasonic cleaners use high-frequency sound waves to create tiny bubbles that gently remove dirt and residue. Simply place your brass casings in the cleaner along with a suitable cleaning solution, and let the ultrasonic waves do their job.

🌬️ Step 3: Dry and Inspect. Once your brass is clean and shiny, it’s time to dry them off. Lay them out on a clean towel or drying rack and let nature work its wonders. If you’re in a hurry, you can use a hairdryer on low heat or a brass drying machine specifically designed for this purpose. After drying, take a close look at your brass casings. Inspect them for any remaining debris, cracks, or signs of excessive wear. Discard any casings that show signs of damage or are unsuitable for reloading.

🧼 Step 4: Polish for Perfection. For that extra touch of brilliance, you can polish your brass casings. Use a brass polish and a soft cloth to give them a final shine. This step is optional but can add a visually pleasing touch to your finished rounds.

📦 Step 5: Store and Protect. Once your brass casings are clean and dry, store them in a suitable container or ammo box. Keep them in a cool, dry place to prevent corrosion and maintain their quality until you’re ready to reload.

      For the first 4 years of my reloading experience, I only used Hornady or Winchester brass. Surprisingly, both gave me great accuracy and reasonably good standard deviation and extreme spread.

            Hello everyone,
            Lately, I have been struggling to find brass for my 300WSM like many others during these times. I came across some Norma brass for $2 per casing. However, I am wondering why Paterson and Starline do not manufacture it. They produce brass for some uncommon calibers, possibly for benchrest shooting, but not for the WSM. I might not fully understand their business model, but it seems to me that making brass with a wider appeal would increase their sales compared to an uncommon caliber that only benchrest shooters would be interested in.

              I also had a hard time finding brass for my 300wsm. Without considering the availability of brass or factory ammo, I impulsively bought a T3 lite SST/SYN for more than 40% below average price.

              I went to purchase Hornady 300wsm brass, but I found Federal Power Shock ammo at a slightly higher cost than the brass. So, I decided to buy both in large quantities. Moreover, I was able to purchase a considerable amount of Winchester 300wsm brass from my local Cabela’s, using my Cabela’s club points, which made the brass virtually free. Luckily, I stumbled upon a 200-count lot of Norma 300wsm brass priced below $1.20 each and bought it.
