I've been looking at kits and reading about reloading ahead of actually getting set up later this year. I notice that many kits (primarily the Lee kits) come with a powder measure than goes on the loading press and dispenses powder directly into the case. I was wondering how accurate these tend to be as everything I've read suggests getting a good beam scale and weighing your load carefully. Obviously this doesn't happen with the powder thrower.
Could the thrower be used separately to throw an underweight charge and then use a trickler to bring it up to correct weight on the scales or are they only useable on the press?
