After reading some threads it seems that BD is preferred over PP with velocity and low pressure in mind. Can you explain why? My manuals state: Modern Reloading 2nd: (Max Loads) BD: 10.4 gr @ 1220 FPS PP: 8.7 gr @ 1240 In my experience both powders are boomers, lots of flash but PP meters better. School me please.
