Checked my notes, 10 rounds of IVI ‘04 MK VIIIz chrono’ed at MV=2484, ES=43 and SD=11.6 from my LB No.4 (.3035 bore/.315 groove dia.). Temp was 60 deg F. Shooting Chrony Alpha Master 15 feet from muzzle.

That same day, 10 rounds of DAC ’56 VIIz chrono’ed at MV=2403,ES=54, SD=21.

174 gr SMK over 42.5 gr Re 15 Reloads chrono’ed at MV=2550, ES=60, SD=19.

I’ve since dropped my 174 gr SMK Match loads to 40.0 gr Re 15.
