[QUOTE="woods, post: 456620, member: 6042"] Just picked up a project for a friend that is a 30 Gibbs. He has 18 old cases [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSC00995.jpg[/IMG] but asked me to figure out how to form new cases. From what I have read the method is to expand the neck to 338 and then form a false shoulder that has a crush fit in the chamber, load a medium load with the bullet into the lands and fire form. The dies I have that I thought might work are: Lee Universal Expander 338 win mag Lee Collet 338 RUM Competition bushing neck die 30-06 FL die 30-06 Lee Collet 30-06 Redding Type S bushing neck die So my initial concept was to expand the mouth of the case to 338 or so and force the 338 Lee Collet mandrel into the neck and neck size just the right amount to match the fired cases shoulder position. But the 338 mandrel does not do a good job and I don't think this will work [IMG]http://img.photobucket.com/albums/v663/bwestfall/CASE%20PREP/DSC00990.jpg[/IMG] the mouth is crooked and the bulge is on one side. I did liberally lube the neck during both processes (expander and collet mandrel). Anyone with any experience? [/QUOTE]
