Re: preping brass
S1, your observations about FL sizers is right on. My beef is that it is almost impossible to know what the dimensions of the die is before you buy them. Can lead to all sorts of headaches. Custom cut dies are just too expensive for me.
So, I neck size. Eliminates headspace, neck donuts, and sloppy fit. With the Lee collet die, I get very concentric ammo too. I figure that to get a proper set of custom FL dies at $200US, I can buy a lot of brass and just throw it out when it doesn't chamber (after 6 to 12 reloads). Don't have to anneal either.
I do have one rifle where FL sizing works the best. However, the vast majority have "production" style chambers and the FL dies just don't fit well.
It is too bad that the SAAMI specs have such large tolerances. An oversized chamber and undersized die and you got problems...
