I think I have settled on chambering my first br rifle in 6BR, but I think I like the idea of "trueing" up the necks for concentricity. Is this totally unnecessary with Lapua brass? If I want to give them a little cut, would you recommend a 270 neck or can you give them a little clean up and be ok with 272. 272 seems to be the std.
Thanks,
