Body Die or Full Length Die for Shoulder Bump?

Yes, my neck die is a bushing style as well. But hey, I like the fact that someone is looking over the others shoulder on stuff like this!! [img]/ubbthreads/images/graemlins/grin.gif[/img] Jim R

Jim,
If you have a regular 30-06 full length sizing die, try it as a body only die.

anyrange,
The whole idea of the body die is to bump the shoulder without touching the neck.
As Abinok explained, a regular F/L die will crush the neck down to an undesirable diameter.

.005 reduction in neck diameter sounds great for BR and a disaster for the field (unless you have a very tight neck). In general not good advice (IMAO).

Listen to froggy, loose the expander balls.

I thought the goal was to neck size so that you achieve .001 neck tension on naked projectiles and .002 on moly. The external sizing is relative to this but doesn't tell us what the internal dimensions are before seating?
This depends on how tight the neck clearance is in the given chamber and neck expansion upon firing then brass bounce back dimensionally.
