i set up my lee classic turret and pro auto disk powder measure and it seems to be throwing an inaccurate charge....i wanted to use about 4.2 gr of unique for 38sp....according to the "book" that came with the powder measure disk 46 should drop 4.2 gr of unique....i am consistently getting 3.3 to 3.4 grs...

1st,The "book" is just a guideline, not the absolute amount that the disc will throw. They purposely make them throw lite, because some people cheap out, don't buy a scale, just rely on the "book" to be right.
2nd, unique NEVER drops well in ANY measure.
3rd, for handgun, it doesn't have to be that exact.
Just get it close, go about your loading.
