I have 3 Ackleys and trim w/the Lee cutter because they trim so squarely. I just let mine grow until they need trimming and trim. As long is the gauge is not touching the mouth of the case...you know your still under OAL. I run the gauge in all of mine each time I reload one, only takes a second. I like my cases to be at max or close to it, I don't like short cases. powdr
