[QUOTE="kiwikid, post: 2015916, member: 56094"] My case resizing does not involve any type of mandrel or expander button. Basically I de-prime and clean the primer pockets, sonic clean and dry. The cases are annealed every firing with an AMP annealing machine and then resized with the Redding bushing die, primed, charged and the bullets are seated using the Redding Comp seating die. It is a bad day if I see run out greater than 0.002" with most of them less than 0.0015". I have found that the Lapua brass tends to have extremely consistent neck thickness which must help with a consistent neck tension as I have a recorded 7.28 fps of ES with a SD of 3.05 fps over 5 shot groups using a LabRadar. Although I own a Foster outside neck turner I have never found the need to use it on Lapua or Norma brass. Good luck with your new loading endeavours and please let us know how it turns out. [/QUOTE]
