Quick Answer
To reload .270 WSM cartridges, use a high-quality brass case, carefully select a suitable powder, and adjust the seating depth to achieve optimal performance. A consistent and accurate reloading process is crucial to ensure reliable feeding and consistent shot placement in various hunting scenarios. Regularly inspect and maintain your equipment to prevent errors.
Choosing the Right Brass
When selecting brass cases for reloading .270 WSM cartridges, look for high-quality cases with a minimum of 0.002-inch wall thickness. This thickness provides sufficient strength and durability for repeated reloading. A reliable supplier should provide cases with a consistent annealing process to prevent excessive hardness or brittleness. For the .270 WSM, use Federal or Winchester brass cases.
Powder Selection and Loading
To achieve optimal performance, use a suitable powder that suits the .270 WSM cartridge. Hodgdon’s Varget or H1000 are popular choices for this caliber, offering a high velocity and good energy delivery. For a 120-grain bullet, load approximately 56-58 grains of Varget, with a seating depth of 2.880-2.900 inches from the case mouth. Use a powder scale and a precise measuring system to ensure consistent loads.
Seating Depth and Bullet Type
Proper seating depth is critical for reliable feeding in the chamber. For the .270 WSM, use a seating depth of 2.880-2.900 inches from the case mouth for a 120-grain bullet. This depth ensures a consistent and reliable feeding process. When selecting a bullet type, consider the intended hunting scenario. For elk and larger game, use a heavier bullet with a higher sectional density, such as the 150-grain Berger VLD or the 140-grain Speer BT. For deer hunting, a lighter bullet with a lower BC, such as the 120-grain Hornady SP, may be more suitable.
