[QUOTE="Ballistic64, post: 144438, member: 3401"] I dont have any experience with the 338-300,but why would a doughnut form just from necking up without neck turning? If you have the neck turning expander coming,the expander should open the 308 neck to fit the 338 neck turning mandrel without having to FL size the brass.After turning the necks you should only need to size the neck back down for the desired bullet tension.A doughnut formation in the brass is usually the result of not turning the necks the proper distance into the shoulder of the case(which does or doesnt matter depending on how far your bullets are seated into the neck.Tell me if Im missing something.Im not trying to critisize at all,just trying to understand something Ive never done yet.
