Not sure as I use the Lapua factory brass straight out of the blue box. The neck tension I normally use (.0015) is not an issue until the brass is checked for thickness and run through the die.

I jam my factory brass .020 with 29.5 gr. Varget and 107 SMK's. Lost one case in about 160 fireforms.

The same amount of tension used when loading for normal use. Keep things consistent!
