First time reloading... got a Lee Perfect Powder Measure and a Lee scale. I'm using Bullseye as the propellant. The manual says Alliant Bullseye's VMD is .1064cc, so I adjust the Powder Measure to drop 5.32cc to get 50 grains, and I'm expecting to measure 50 grains in the scale. But it's consistently coming up to 4.97cc! This is the first time I'm going through the Powder Measure hopper (manual says to go through a whole hopper so graphite from powder coats nylon internal parts) and I'm not done yet. Is this normal? I'm halfway the hopper now, and the readings are consistent. If I'm reading and adjusting everything right, that's a 3.29 grains off what I'm trying to hit. Any suggestions? Anyone has the same setup, and had similar issues? Thanks for any help.
