big al hunter, I have 3 different samples of the same bullet. One is sized and tumble lubed to .356, the PC sample has also been sized to.356 after coating and they are the ones I cast which are also tumble lubed and sized to .356.

I have measured the length of the bullets and their diameters and with just a .000 place caliper I cannot discern a size difference.

I am also loading these on a Lee 3 hole turret press and each finished round is measured for length before being put into the box. Also as this is a work up all the bullets were weight sorted into groups with a variance of .04gr.

I was called away before I could try this same setup with a tumble lubed bullet but hope to test that yet tonight before I go to bed.
