Looking for powder advice. I recently started loading for my new 338WSM build. Nosler M48 long action, Benchmark Carbon Fiber 1:10 20” barrel, 9.5” Sully’s arms suppressor. I’m shooting 230 ELDX around 2640 fps using W760, and just under pressure signs. Would 6.5 StaBall or Superformance be worth trying?
