I like the Lee dies for the price and that is it. The collet die for my 270 doesn't have enough neck tension but you can get undersize mandrel for a couple of bucks from Lee. The 223 dies are great. Not as big of a hassle as the Hornady New Dimension that I tried. I didn't like the Hornady seating die.
My first recommendation is the RCBS dies. For economy get the RGB Lee dies. In either case I buy RCBS or Hornady lock rings separately. The Lee ones are a joke. My biggest misgiving about the Lee dies are that the seating stem doesn't lock in place. It has a rubber o-ring for tension if I remember right. I have to double check OAL. Reed gave me this tip by the way:
"I'm no fan of Lee, but....two things you can do to solve this. #1 cut a lite chamfer on the ID of the brass. Next, do NOT set up Lee dies like they tell you, most of their dies will cause what you have shown. Run the brass all the way to the top, then screw the die down until it makes contact with the case (not the damn shellholder) then seat the bullet. If you need a light crimp and don;t have the FCD, seat all your bullets and then go back with the seat stem screwed way out and adjust the die for a light crimp. "
Now that I have typed all of this.................just buy RCBS dies, dude.
