[QUOTE="Trnelson, post: 614917, member: 42308"] Duplex loads are WAY at the deep end of the pool. Furthermore even when they are used the end result is and must be a fully compressed load where there can be no "intermixing" of the powders or REALLY BAD THINGS LIKE DEATH CAN HAPPEN. I have read about guys using the ultra slow government surplus powders such as WC867 or 874 as the main charge and replacing a couple grains with a "booster charge" of something like Unique or Bullseye right on the primer and then carefully using a drop tube to place the main charge. They were using cases no smaller than the 300 Win Mag using 220 to 230 grain bullets. They reported muzzle velocities in the range of 2,400 to 2,500 fps. So there was no performance advantage to be found with what they had done. It was to done to "get rid" of the cheap surplus powder. Long story short IMO a waste of time and I personally wouldn't mess with it without the ability to pressure test. [/QUOTE]
