My 2 favorite powders in them are IMR 4350 and Re-22. These two powders are often over looked because their maximum velocities are already about 100 fps slower than some other powders. and they don't throw as consistent of powder charges as some other powders so they require a small amount of extra time at the reloading bench. The Big bonus that I find in these two powders are a very consistent velocity across the chronograph, most register as a duplicate. I don't ever use the std. deviation button because I look for the maximum velocity difference between the slowest round and the fastest round ( I never have been able to tell which one of my rounds are standardly deviated by looking at them ). 15 fps is what I look for, and am certain that the majority of that spread is from my inability to shoulder the rifle the exact same way every time, the more not movable the rifle sees me and the tighter I pull in on my recoil pad the higher the velocity gets and the opposite is also true. I am happy to see a trend of people actually starting to give realistic appraisals of average accuracy instead of the accidental best they have ever shot. This brings me to the wind, The Wind witch isn't evil, she requires a long courtship!
