When using once-fired brass, collect it from a reliable source and ensure it is of good quality, inspecting for defects or damage. Cleaning the brass is a good first step to remove any debris or lubricants. Trimming the brass to the correct length is essential for consistent neck tension and proper chambering. Use a chamfering tool to smooth the case mouth, making it easier to seat the bullet. Deburring the inside of the case mouth is also important.
Primers
Primers are the ignition source for your cartridges. Large Rifle primers are typically used in the 303 Savage. They are categorized by the sensitivity to the striking pin. Choose a reputable brand of primers and use them as directed. Primer seating depth is important for consistent ignition. The primer should be flush with the base of the case or very slightly recessed. Improper seating can lead to misfires or inconsistent performance.
Bullets
Bullet selection is critical to the overall performance of your 303 Savage loads. The 303 Savage typically uses bullets with a .308-inch diameter. The range of available bullet weights for the 303 Savage allows for versatile loading, from lighter bullets suitable for target practice to heavier bullets that can be effectively used for hunting medium-sized game.
The ideal bullet weight for your rifle depends on several factors, including the intended use, the rifle’s twist rate, and your personal preferences. Bullet types vary widely, including full metal jackets (FMJ) for target shooting, soft point bullets for hunting, and even specialized bullets for long-range performance. Each bullet type offers unique ballistics and terminal performance characteristics. Consider the game you are hunting, the distances at which you are shooting, and the desired expansion characteristics when choosing the bullet.
