Re: Dreaded Doughnut????????
Well I just got off the phone with Ken from K&M. Basically he said all I need to do is just run the case over the expander just short of hitting it on the die. Easy enough. He said what you need to watch for is after you size your brass but not expand it, look into the neck. If you see a usually non uniform bulge starting in the neck, just in front of the shoulder then you should only expand to the point just short of the "doughnut". Then cut it out with the reamer. if you run the doughnut over an expander it will just smash the doughnut down and force the material back into the shoulder area. What this causes is an uneven thickness of your shoulder. So it's better to cut out the doughnut to keep things even.
What the cause of the doughnut is the brass flowing forward from the shoulder area into the neck area. He said I will probably never have the doughnut problem as i dont get that many shots out of my brass before I can them on my STW, maybe on my .243 though.
I hope this made sense, I am not that great at explaining details.
