Looking for some guidance ,how do you determine what size of bush required for your given calibre for a F/L Bushing die ?
Measure the diameter of a loaded round.
Subtract 2 thou from the diameter you get. Try that bush and also get one - 1 thou bigger and another one - 1 thou smaller. Try them and see how they go.
Keep in mind your necks may vary in diameter by manufacturer and by lot. I've generally bought a range of bushings for any bushing dies that I have.

Hi,
The supplier of the die said to measure the neck of a new unfired case ? Is this correct ?
