Quick Answer
Custom loads for .270 WSM can be worthwhile for hunters seeking optimal performance, but it requires research and precise reloading techniques to achieve consistent results.
Understanding the Benefits
Custom loads for .270 WSM can offer advantages in terms of bullet performance, recoil, and overall effectiveness on game like elk and deer. For example, a hand-loaded .270 WSM cartridge can achieve a velocity of 3,200 feet per second with a 130-grain bullet, compared to the standard factory load of around 3,100 feet per second. This increase in velocity can result in a more efficient transfer of kinetic energy, potentially leading to cleaner kills.
Reloading Considerations
When reloading for .270 WSM, it’s essential to pay close attention to the case capacity and chamber pressures. The .270 WSM cartridge has a relatively small case capacity, which requires precise powder charges to avoid over-pressure. A safe starting point for reloading is to use a minimum powder charge of 43 grains of IMR 8208 XBR for a 130-grain bullet, and adjust from there based on desired velocity and pressure readings. It’s also crucial to use a high-quality powder scale and follow proper reloading procedures to ensure accuracy and consistency.
Practical Application
For hunting elk and deer, a custom load for .270 WSM should be designed to deliver a balance of velocity, energy, and expansion. Aim for a velocity range of 3,100 to 3,200 feet per second, and use a bullet with a suitable profile and weight for the game being hunted. A 130-grain bullet with a ballistic coefficient of around 0.45 is a good starting point, but experiment with different weights and profiles to find the optimal combination for your specific needs.
