6 Dasher

[TerryPohl]

Just measured my new Lapua 6BR brass and the necks are .268 I am having a tight neck,.266 ) Dasher built. I was going to fire form the COW method by expanding up to 25 cal. and use a standard BR resizing die to neck back down. My question is will a standard 6BR die size it down enough to do this. Are will I have to use a bushing die? I have a tight neck 6BR now but the bushings are squair cut and I do not know if they will work.
Any advice will be greatly appreciated.

Thanks for the help Gunamonth. The mesurments was from a unloaded peace of brass. I forgot about pulling the expander ball out when necking back down. This shpuld work.
