I know this has been asked and I looked for it unsucessfully.. What is the neck diameter of a .308 loaded with Lapua brass. I'm ordering dies and I want to order the S bushing at the same time.. Thanks
 
Thanks for the link, but I had seen that and I understand how to determine the bushing I need IF I have a loaded round with that brass with which to measure, which I don't. With the consistency of Lapua brass I had hoped someone would pass that dimension on to me so I don't have to buy 6 differet bushings..
 
Hard to pick just one bushing, if your going to buy the brass, do it, and pick what bullet your gonna use and put the two together and measure...then you'll need to decide if .002 neck tension shoots better than .003 or does .003 shoot better than .004 see what i'm getting at.

I have 3 differant buttons i use for my 30br depending on what bullet I use.
 
I load .308 Win. using un-turned Lapua brass w/SMKs and Bergers. The loaded rounds measure .338 at the neck. I've had best results with a .336 bushing...
 
.335 to .336 bushings is what i use with Lapua brass and Sierra MK
or Berger BT with good results.
