Getting ready to load 270 WSM, my question is about primers some load data is for Magnum primers and some is for Large Rifle using same powders just different manuals. Ask my dad and his only thought would be for ball type or short grain powders maybe use the Magnum because of the load density of those powders verses say longer extruded powders such as IMR 4350 using Large Rifles
