[QUOTE="Mikecr, post: 1212745, member: 1521"] I think you're confused on the terms related. There is: -Cartridge overall length (OAL, case head to bullet tip) -Cartridge base to ogive (CBTO, case head to a bullet nose datum behind the tip/near land contact point) -Same lengths for bullets alone OAL is truly meaningless to anyone. CBTO is very meaningful while you make it so (through testing). The bullet parameters are mostly meaningless to CBTO, as CBTO is set with your die and verified correct (by you) regardless of bullet. It's pretty standard in reloading to test for best bullet seating depth, measured as CBTO, adjusting the seating die to reproduce this, and never changing this for the life of the barrel. [/QUOTE]
