[QUOTE="Greasegun, post: 1827165, member: 112196"] I have been able to get SDs under 5 by bushing FL sizing followed by mandrel expanding, without any neck turning. This is using Lapua brass. My runout with seated bullets is =<.002". The only thing I havent been able to achieve is 1/2 MOA groups on paper. Would neck turning help this at all? Its a factory chamber so there is a lot of clearance around the neck dia. [/QUOTE]
