Would this measurement give me my throat length if I seat my bullets to just touch the lands. Measured base of case to ogive with a comparator ( ogive is just touching lands) 2.927. My cases measure 2.615 after trimming. 2.927-2.615 = .312. Is .312 my throat length. This should give me the length from the top of the case mouth to the lands since the ogive of my bullet is just touching the lands.
