Ed here- It takes a bit of work and they only are
good to make the 1" bore ones that match the Owen's doubles
that he had Rocky Mtn make for him. First I turned the base
down to 1.093", then swaged the sides from base to shoulder
straight. Then expanded the neck to 1" id. Between every swaging
and expanding I had to anneal top half the cases. Took 3 swages
and 3 expanders. I left rim same diameter as it is.
RMC can make cases for about 20 bucks each. I had to improve compound
linkage leverage on the ammomaster to do this.Ed
