How to avoid common reloading errors with .280 Remington?

Measuring and Calculating Accurately

When reloading .280 Remington, accuracy is crucial. Measure your case capacity and calculate the correct powder charge based on the type and grain weight of your powder. A common mistake is underestimating the case capacity, which can lead to over-pressuring the rifle. Use a reliable powder scale and case gauge to minimize errors. For example, if you’re using H4895 powder, a safe starting load is 44.1 grains for a 130-grain bullet. However, this can be adjusted based on your rifle’s performance and the type of hunting you’re doing.

Seating Depth and Bullet Weight

Proper seating depth is also essential for optimal performance. The .280 Remington has a relatively short case length, so seating depth must be carefully managed to prevent over- or under-seating the bullet. A general rule of thumb is to seat the bullet 0.020-0.030 inches from the lands, depending on the type of bullet and the desired expansion pattern. For mule deer hunting, a heavier bullet weight like 150-160 grains is often preferred for its expanded energy transfer and stopping power.

Rifle and Bullet Compatibility

Lastly, ensure your rifle and bullet are compatible with each other. Using a high-BC (ballistic coefficient) bullet in a rifle with a shorter barrel can lead to bullet instability and poor accuracy. Conversely, using a lower-BC bullet in a longer-barreled rifle can result in excessive bullet deflection and loss of energy. Consult your rifle’s manufacturer guidelines and bullet selection charts to find the optimal combination for your .280 Remington rifle and hunting objectives.
