Hi,
The manual of cartridge conversions talks about expanding the neck of a 30-06 before putting it through the Whelen die. I’ve also read that some just put it in the whelen die.
On the former - I’d be grateful for leads on a tapered expander for just such a purpose. LE Wilson doesn’t make one that big. Do I need a custom tapered expander or is something out there I haven’t found?
Thank you
