Re: Redding neck sizing bushing die

I'm with you most of the way but I prefer to use a Sinclair Expander die rather than the expander "ball" in the sizing die. I am of the school that a "ball", when drawn through the neck is free(er) to follow the variations in brass composition than a mandrel like that used in the sinclair. Totally agree that using the proper bushing size, along with neck turning to give a more uniform neck thickness, pretty much precludes the need to "move a lot of metal" when expanding. With my method, for me, it's more of a check on what I can expect for neck tension and insertion pressure when seating a bullet.
