243 Winchester Brass neck thickness

[loudandproud]

Does anyone have a recent batch of .243 Winchester brand brass? What is the average neck thickness?

I am looking to form 6 SLR brass with it and need to buy a bushing relatively close to the appropriate dimension. I will be running an expanding ball initial so Im not terrible worried about "exact".

Ill fine tune later...

I just formed 200 Win, not going to measure, not sure I have the right tools, but a 269 bushing should let you one pass the forming.
I use a reg die, no expander, then expand with a carbide expander(die), then go with a 268 bushing for a 105 hybrid, Rem brass I use a 269 bushing.

I can't help, my winchester brass has all been neck turned. I use a regular Forster F/L die with an expander ball and I turn the necks just enough so the expander ball does very little expanding.
By the way, 6SLR using a 6XC die turned out .122".

Winchester Lot KD51 is running 0.015" +/- 0.001".
