Yeah at 300 a chargemaster works like a champ, especially with ball powder. Of course I load for 1000 and beyond so it does matter for that, especially in the prone matches. As far as the Lee, if it works for you then rock on with it. It didn't work for me though. It was just too many little issues and with the little time that I have, I'm very happy to pay a little more for one that works all the time and doesn't have those little hiccups. Honestly, I doubt I will ever buy another primer. I prefer hand priming and the FA just works great, and I actually got 2 so I could just leave one for small and one for large, while also always having a back up. Seriously, if anyone wants the Lee I will sell it very cheap.
