I was doing some reloading this weekend and after full length resizing 50 or so 300 Wby brass,the part that goes in the neck and that holds the rod to knock out the primer stripped the threads on the shaft.I stole the guts from a .308 die and kept going though.I called RCBS customer service this morning.Their response was "We are sure sorry to hear that,please give us your name and address and we will ship the whole replacement shaft to you immediately".You cant get any better than that.I didn't have to send the broken part back and then wait on a replacement.RCBS will continue to have me as a loyal fan and user of their products.
