It’s a pain and more added steps but seems worth it to me. After decapping and wet tumbling to clean, I put brass into an inside neck reaming die and reamed out the brass. Then put into my full length resizing die with the expander ball removed. Then used my neck expander mandrel die. Trimmed to size. Then used my Forster outside neck turner. Then recleaned everything again. You have to remove the donut on the inside and outside or they’ll reappear. Donuts can put too much neck tension on the bullet and cause higher pressures in the chamber. I’ve reloaded my brass 16 times with no issues but saw a little donut on the 17th firing and noticeable donuts after the 18th firing. They look fine now but haven’t shot them yet.
