Thanks Larry
I just received my Neil Jones F/L sizer but haven't used it much, the Lee I had worked the brass too much so I was only neck sizing...now im only pushing the case wall about .002 at the most compared to .008 with the Lee.
I'm going to shoot my next match with what has worked so far and will start F/L sizing after that, the RP brass I have been using is about on it's last leg.
I will definatley F/L size everytime with the new Lapua brass I have...you are correct, there is definately alot of pressure at the base.
