It’s another procedure to add to the reloading sequence .Some say that it makes a difference, if you are using expensive brass it’ll keep it ‘good’ for longer .
Is it worth it? Also it depends upon what you are shooting such as F class where one needs all the help one can get 😁
I do have one of their earlier machine but have not got round to using it yet, similar ones are available along with considerably more expensive machines .
