As others said, I'd suggest buying the Lee scale. Then dip and dump back in the powder bottle a few times to make sure your consistent with the dipper.
I have a nicer press but still mess with the Lee loader just for fun. I use the $50 lee hand press to deprime and size then prime 50 or 100 at a time then take that box of primed with the Lee loader and just have to bell, drop the powder, bullet and crimp.
