Ahh, I would measure the brass then re-size then re-measure.briannmilewis said:Can I make a rough prediction how much a neck will grow in length when I neck a case down from 257 to 224?
I assume it would depend on the thickness of the case and the amount of neck-down in the process?
Or must I experiment?
Simular to the 22 Savage High Power.briannmilewis said:Had some feedback that you can take 25-35 Win brass and run it thru a 219 Zipper FL die (258 -224) and you are good to go, without trimming or turning the neck. As the cases are very similar, maybe that is where it doesn't matter much.
