About a year ago, I had the good fortune of getting a great deal on a .300 WSM. Before I bought it, I checked the reloading manuals to see what powders were commonly used in that cartridge. To my delight, many were powders I already had on hand, including a 8# jug of StaBall 6.5. I ran a ladder test of StaBall and 168 TTSX's and settled on 66 grains for what has become one of my most consistently accurate combinations ever, in any rifle. Velocity is in the 3050 fps. range. I am tickled to death with this combination. I wasn't sure how many of you .300 WSM shooters have tried StaBall 6.5 in your loads, but I can tell you it is definitely worth trying.
