Someone Check My Neck Measurements For Bushings

[sawacs]

I am trying to dive into the world of sizing case necks with bushings and wanted to make sure I am ordering the correct bushing. The bushing die is the Redding Bushing Neck Die #56415 for the 6.5-284 cartridge

I am using the KM expand mandrel/die with the window that measures 0.264. After expanding the neck and immediately loading with a 139 grain scenar,140 Vmax, or 120 and 123 scenars, my case neck measures 0.294.

Would it be safe to order a .293 and .292 bushings to get started? I also have a KM neck turning setup coming in and plan on turning the necks just enough to make them uniform and no more. Lets say I turned the necks and took 0.0125 off, would I need to subtract this from the .293 and .292 bushings and go with .292 and .291 bushings?

Edit: I should probably run a case through the expander, turn the necks, load the dummy round then measure to get the correct size bushing correct?

I hope all of this made sense..

Thanks,
