Purchased some new Lapua 6.5 x 284 brass. I am trying to to determine how to treat this new brass vs a fire formed piece.
I just swapped out the standard no frills RCBS for the Redding Bushing dies hence these new questions.
A loaded round measures .2925 OD on the neck. The new brass is .2895 OD. Fired brass before resizing comes out at .2975. Assuming I take redding's advice and use a bushing that is .001 smaller than the loaded round it will have no effect on the new brass since it is already considerably smaller than the target size. Will this brass all have to be fire formed before I can get a consistent neck tension? Also, will I have to resize the fired brass multiple times stepping down the bushings since it is 5 thousandths from where I want to end up.
Thanks for the help

Don't fret about it.....load the stuff up and shoot it. After firing you'll find out that the 'springback' has occurred, and things have sorted themselves out.
You don't have to worry about Lapua brass, especially their neck uniformity. Don't sweat a couple thou's at this stage.....the brass is as perfect as factory brass will EVER get....load it and shoot it and you'll see that that there's nothing to worry about.
