Good morning folks,
Does anybody happen to know the nominal length for Hornady's 124 Gr. and 147 Gr. FMJ RN bullets? I can't seem to find it online anywhere. I'm just starting to work up loads for some RMR 124 and 147 Gr FMJ bullets (just opened the bags and measured some sample bullets this morning), and would like to use Hornady load data as a starting point.
They'll need to plunk in my CZ85, and with RMR's more "blunt" nose profiles this typically means I'll be using significantly shorter COAL than the published Hornady Data. Generally, the blunter nose profile also means a shorter bullet, so a shorter COAL actually produces similar remaining case volume for the powder charge so pressures don't spike.
This is what I found when working up loads for their 115 Gr bullets, but I actually had the Hornady bullets on hand to measure for those. I don't have any of the Hornady in 124 or 147 Gr, but I'd like to know the Hornady bullet lengths so I can confirm for certain that I won't be reducing case volume.
Thanks very much!
