Stay away from the Lyman. Mine began to throw charge weights different that what we displayed after a couple years of use. I verify intermittently with a beam, but I observed difference in case fill before catching it with the scale. Lyman told me how to reset the unit. It didn't make it thru another week without a relapse. Trashed it, and went back to throwing charges. Unless I start shooting beyond 600 yards, I will be using Redding, and RCBS powder measures.
