In some 243W and 30.06 loads I'm using WR Primers as direct substitute for Federal 210. Accuracy, velocity POI haven't changed. One differebne is WR primer cups are deeper / taller than the Federals. I find in my Norma brass I have to seat WR Primers with a little more grunt to ensure they don't project above case head level. But in Sako and Remington brass they seat below head level.
