Getting ready to start loading for my new 243W and am going to use a Redding competition die set. What bushing do you guys use for the neck sizing die?

I've got 100ea of Lapua brass to get going with for load development but will likely use Win brass for matches where you lose a bunch, if not all.

Many thanks for guidance.

I believe the rule of thumb is measure the case neck on a loaded round, then subtract .003. That is a place to start.
Buy a couple and then see which works the best for you.

I have a few different sizes for my 6mm's.

Good Luck

You have to measure your own brass.
Just seat a bullet that you are going to use.
Then measure the case neck diameter and subtract the amount of neck tension you want.
As a general guide .
.001 = low tension for hand fed rounds.
.002 = Medium , general use in bolt actions and lower recoil cartridges.
.003 Autos and medium hunting ammo .
