I only use FLAT Point seating plugs for flat points , and ROUND NOSE seating plugs for round nose bullets. This gives the best OAL consistency .
When establishing over all length ( OAL) I always do the \”Plunk\”test to find the Max OAL for the attended firearm, than go from there. The round my pass the plunk, but still need final adjustment to run consistently. RN and Flat points bullets will differ in OAL. Every weapon is different. It is possible to find the \”sweet\” length to satisfy MOST of your guns of the same caliber.
