Re: Neck dies....any reason to avoid Lee collet dies?
Back when I had a .30-06 rifle I used a Lee collett neck sizer die with great results.
But now...
Strangely, I am able to load sub MOA accurate rounds in .260, .308. and .300wm, all with Lee full-length sizer dies, all on a Dillon 550.
No co-ax press, no bushing dies, no concentricity gauge, minimal case prep.
