I have a lee Perfect powder measure (I know its not the best) that I have used for 2000 rounds so far with no problems. Recently I acquired some fine grain powder. Before I had only used flake powder. While using the fine powder the Lee Measure becomes stiff and unusable after only 25 rounds. Has any one else ever experienced such an issue? Needless to say I am in the market for a replacement. What would you suggest as a cost efficient replacement?
