You need a .243AI bushing die with the correct bushing for your neck tension.

Either a .243AI seating die with a .22 cal. stem or use the reamer to cut a Wilson die blank for your seating duties.

^^^what these guys said^^^

Use the right tool for the job.

I neck down Lapua .243Win brass with a Redding Type S .243AI bushing & .251" Ti bushing. And the .243AI seater works fine...

Things are only as complicated as you make them
