Im ordering a set of Wilson dies for .308. Bullet is 168 Sierras, brass is Lapua. Can someone give me a heads up on what size bushing. Im not neck turning. Thanks.
 
The smartest way I've heard to get a starting point is to measure a sized case after you've seated a projectile in it, then go for a bushing maybe .003" smaller than your other reading.

The other option is to use the Lee neck collet die to size & set it up the way John Valentine has explained in a thread he wrote here: http://benchrest.com/forums/showthread.php?t=49899&highlight=collet

I should confess that I prefer the Lee for chambers that don't have tight turned necks.

If loaded round neck diameter measures .334", I would recommend buying a
.330" and also buying a .331" bushing for .003" and .002" neck tension respectively.

Lapua cases normally do not need to have case necks made concentric, but it is worthy of checking, and if slight neck turning is needed, buy additional smaller diameter bushings as needed.
