Well, if you not after every little tiny bit of accuracy then lee will work just fine.

Remember if you get a collet dies, you also will need a Full length die for new brass.

Here's the deal. Your doing load development. You see promise in a load. Then you get a flyer out of no-where. You start questioning everything. Runout is a biggie for some calibers, othes like a 308win doesn't seem to affect it.

i have done a lot of tests with runout. and have separated out different batches from real bad at .010", then bad, from .007" to .010", then ok from .004" to .007", then almost perfect .000" to .003". What I notice on most rifles is things don't make a huge amount of difference until you get past .005"

But I have also found that even with perfect match dies you can screw up neck or bullet runout and found the shell holder slop to be the issue, or squareing of the dies.
