Value of Neck Turning 6BR Lapua Brass

[RonAKA]

I have been looking through many posts and have concluded that the consensus seems to be that neck turning is falling out of favour. I guess my basic question is why? Is it that the Lapua 6BR brass is so well quality controlled that there is no variation in neck thickness that needs to be corrected? Or is it that a small variation in neck thickness does not affect accuracy?

My application would be a factory Savage LRPV in 6BR so I'm expecting that the chamber will be large to start with and neck turning will not be needed for size. And, if I do neck turn minimally to clean up any variation in neck thickness, then the neck clearance will only increase further.

Folks are seeing that there is no need to neck turn unless it's called for in a existing chamber... Very few factory chamber can make good use of them..
Good consistent necks will shoot better than those that are not, no matter what they measure..

So, to be sure I understand, I think you are saying that in a factory chamber turning the necks is not likely to improve anything, but it wouldn't hurt. Sound right?

With the generous factory chambers, turning necks increases the neck tolerances and shortens brass life.

Yes, Alf, that is my concern too. I see one poster in another thread feels their Savage chamber is 0.271-0.272", so if accurate, perhaps not that bad. Expect loaded rounds will be about 0.269" not turned. 0.268" after clean-up turning??

The more time you spend turning the necks and messing with your Lapua brass, the less time you have for pulling the trigger. JMHO, Mike.

The only true way to know is to do a chamber cast, then there's no guessing.
