I have for sale a CH4D neck sizer die for the 257 Roberts Ackley Improved in good shape. I just checked and a new one of these is priced at $87 and a Redding is priced at $66. How about $40 shipped. Payment by money order, I don't have PayPal. First "I'll take it" followed by a PM gets it.
Going through reloading stuff currently and have some brass I can spare. Shoot me your info via PM and I will let you know what I have when I get done going through it in the next few days.
