With his fired cases, John Hoover runs the case through a neck-sizing only bushing die. He tries to set the bushing to only size about 50-60% of the neck.” His three-stage process is: 1) Full-length size each case; 2) Expand neck; 3) Neck-size just the top half of the neck.

I believe I'll continue to partial neck size. If it works for John, I certainly don't have the credentials to argue.
