Hello Guys

Can a reamer for a rimless cartidge (say 257 Roberts) be used to cut a rimmed chamber (for say 257x57 rimmed)- assuming that the rim rebate would be cut separately. Also would a 257 Rob size die (with appropiate shell holder) work ok with the rimmed version??

Yes, I've done that several times. I cut the rim recess with a small boring bar after the chamber is cut and before the barrel is removed from the lathe.

Many rimmed cartridges have also had the rims turned down in a lathe so they can work through a bolt action rifle without having to enlarge the bolt face. The 219 Wasp was done this way in Benchrest rifles that had a 30-06 size bolt nose.

Works great either way you do it.

Thanks Ray

I'm still thinking about single shots hence the rimmed thing, and getting reamers (here in New Zealand) in anything a bit unusual can range from being a real bear to impossible.
