Unique has always been a tough powder to meter because of the large flake size. I have been using lee equipment for years, never been disappointed, while it is not as pretty or fancy as some of the heavy cast iron stuff it has served me well. With coarse powders like Unique it helps to keep the hopper level consistent,
I always through several test charges to settle things in, if you through the handle the same way every time you can get consistent results.
