[QUOTE="Conrad, post: 1459184, member: 9177"] Ran a little test on some 6xc brass taking it to 6.5 with only a Sinclair expander mandrel. Lubed neck and mandrel. Checked run out before necking up. Ran smooth, and run out did not change. The case did shorten about .0045", but I'm thinking a brand new case will be even smoother, and really not worried about that shortening affect, not to mention .257 will be an even smaller jump up.
