[QUOTE="Mikecr, post: 662815, member: 1521"] I agree with bullet bumper's posts here, except the re-turning after fireforming. That won't work well, and should never be needed. Best to turn brand new necks that have been expanded/turned with a good system(i.e. SINCLAIR). Take it up onto the shoulders a bit with closest matching to new brass shoulder/cutter angle, to initially eliminate donuts from forming. After every firing & downsizing of necks, run the Sinclair mandrel through each to drive any thickness variance outward for straighter bullet seating. If you heavily FL size donuts will eventually show up, and if a problem, this can be managed with a reamer. You will never need to ream otherwise. Keep it simple(not cheap) and you'll have good results. [/QUOTE]
