I first loaded all of the test loads on the LNL. Then when I found the one I liked ( the 4831 load) I also threw the powder on the charge master. My LNL powder measure gave no indication that it wasnt accurate, in fact, it threw 20 test charges all on the money. Its just hard to break the charge master habit. Then, I guess if I'm gonna do that, I may as well seat on the rock chucker too. Defeats the purpose of the progressive doesn't it?
