For reloading purpose particularly for an AR15 in which all cartridge am I understanding the terms correctly? If I read that coal is 2.250 it is only referring to the length of the brass cartridge and o.a.l includes the base of the cartridge to the tip of the bullet that is already seated or c.o.a.l includes the seated bullet as well?
I tried doing a search but no luck.
