Verrry Interesting!
This thread is a good lesson for handloaders who ask for a COAL for some unidentified, off-the-wall 230gn RN bullet. So far, there have been bullet lengths reported for 7 different non-hollow point 230gn RN bullets (plain lead, plated, jacketed, etc.) and they run from 0.634 to 0.674 inch long.
If the same seating depth is assumed, the COAL's could differ as much as 0.040"!
The shortest possible 45 Auto bullet weighing 230 grains (with 0.452" OD) would be only 0.500" long, so keep them cards & letter comin' folks. Someone's bound to have a 230gn RN (non-hollow point) bullet shorter than 0.634" (the shortest reported so far).
