"Any good quality dies like RCBS or Redding will work just as well. Unless you are shooting a precision bench rest rifle, I doubt if you would ever see any difference between the Lee dies and the others."
As a very long time reloader with a lot of dies from all makers but Dillion, I fully agree. Thing is, the others cost MUCH more than the Lees! Get the Lee Delux set and add a Factroy Crimp Die if you wish, that will give you total flexiblity.
I deer hunt with a 30-06. .243., .35, 7 mag. Sometimes I use neck sized ammo, sometimes crimped, sometimes neither; it depends on the load I'm using and which is better for that specific load. Nothing is automatically better or worse than anything else, have to test it to find what any rifle and the load prefers.
IF I crimp or neck size it WILL be with a Lee no matter what other dies I may use.
