If you want more of a " true " wadcutter load ? In a magnum case load 3.5 grs of Bullseye powder and load those 240 gr swc's " backwards " with the base of the bullet showing . Seat the bullets full depth till the base is even with the case mouth . I have shot these @ 20 yds with real accuracy . Makes a great target load . I suggest a bench rest or sand bags to really enjoy the accuracy . Regards, Paul
