What Are Common Reloading Mistakes For .375 Ruger?

Insufficient Case Preparation

When reloading for the .375 Ruger, one common mistake is insufficient case preparation. This includes failing to properly clean the case, neglecting to check for signs of wear, and using cases that are too thin or too worn. To avoid this, always use a case gauge to check the case thickness and a case cleaning brush to remove any debris. It’s also essential to inspect the case for any signs of wear, such as scratches or dents, and to discard any cases that are damaged.

Incorrect Powder Charges

Another common mistake when reloading for the .375 Ruger is using the wrong powder charges. The .375 Ruger requires a specific amount of powder to achieve optimal performance, and using too little or too much powder can lead to inconsistent results and potentially catastrophic failures. To avoid this, use the manufacturer’s recommended powder charge, and always use a digital scale to ensure accuracy. For the .375 Ruger, a good starting point is 90-100 grains of IMR 4831 or H4831.

Inadequate Bullet Seating

Inadequate bullet seating is another common mistake when reloading for the .375 Ruger. This can lead to inconsistent velocities, poor accuracy, and potentially even catastrophic failures. To avoid this, always use a bullet seater die to ensure the bullet is seated correctly, and check the bullet seating depth with a micrometer to ensure it’s at the correct depth. For the .375 Ruger, a good starting point is to seat the bullet at 0.040-0.050 inches from the case mouth.
