[QUOTE="woods, post: 404751, member: 6042"] With a OD of .335" and neck thickness of .0145" then the math would be: .335"-.0145"-.0145"=.304" for a bullet grip of .004" That is a little strong. Perhaps if you used a .338" bushing for an OD of .337" (after springback) then you would get a bullet grip (or neck tension) of .002" and that might make a difference. A set of pin gauges [IMG]http://img.photobucket.com/albums/v663/bwestfall/BULLETS/DSCN2124.jpg[/IMG] might give you a surprise on how the actual dimensions of the ID of the neck. It has surprised me sometimes. [/QUOTE]
