Hi all,
My Lapua 338 brass comes out of my gun with a neck runout of +/-.001", when I run it through the Redding neck sizing bushing die it comes out at +/-.004". I've tried 2 different bushings, with and without the neck expander ball, with and without mica. Cleaned die completely and nothing changes. I have 3 other redding bushing dies in different calibers and they all make the necks +/-.002". Any suggestions or do u think I have a bad die.
thanks.
P.S. Using an RCBS Rockchucker
