Spending some time load testing with my .300 S.A.U.M. ... I am putting a couple new bullet combo's to the test with mixed results. I've found the Nosler J's in 168 grain are setting into nice groups at around 2825 fps, and conversely, the Sierra Match Kings in 168's are holding tight down at 2680, which didn't surprise me as they are pretty close to .308 ballistics.
