Well... One of these things, H4350 and IMR4350, is not like the other...
Same rifle. Same charge weight. Same bullet. Same seating depth. Slightly cooler-ish. Different primer. I switched primers to Winchester WLRM. That kind of screws up the "sameness" but it is what it is.
H4350 (3,045 - 3,100 fps)
Shot string #9 is suspect imho.
IMR 4350 (2,985 - 3,040 fps)
