.271" neck diameter

[dbaird]

Came into posession of a very nice 6br with a .271" chamber. I have read that the .272" is a no turn with Lapua brass-(brown and blue box). Will I need to turn the cases for this .271" neck?

I have .271" neck and have had not had to with either of the blue box lots that I've used.

Recently measured up my brass( Lapua 6 mm BR) to specify a Redding bushing die. The necks measured about .268/.269 with the bullet seated(Berger 105 Hybrid). My chamber is a Shilen with .272 neck and there is no issue. Went ahead and did a very light neck turn to make sure they were uniform and I probably could have passed that step.
