How would I form a 223 shoulder and neck, on a short 223 case?

Contact Butch Lambert - he has a set of case forming dies. Will allow you to make a 17/416 Rigby if you wanted.

His contact info is here...and some pictures.

That's the set I was talking about.... ;)

You could always go to the .22 Squirrel..shortened 22Hornet.

Folks: I have settled on the 223 Short, parent case 223 Rem, or 221 Fireball to begin with to save on custom dies during development.

Thanks for the valuable input.
