I have accually put together a hunting rifle chambered in 30 BR. During break in, I have shot a few different bullet using H4198. I found the Sierra 150gr FN bullet to be the most accurate so for, 5 shots at 100 yards. I have not run this over my chrony yet. Are there any other powders anyone can recommend I try? I would like to try the Sierra 135gr FBHP for whitetail.
