I thought I'd heard of one standard 99 that had been converted to 284.. but maybe I'm mis-remembering?
But another prototype 284 is out there somewhere with an RD serial.
I have held in my hands a 99DL in 284 that had an "RD" prefix. I believe that either Jed, or Jed's buddy Lynn, may own that rifle or may have owned it. I was contemplating buying it when a hand reached past me and snatched it out of the rack at the Kittery Trading Post about 27 or 28 years ago. There were 3 RD prefix 99s in the rack, a 22-250 99C, a 284 99DL, and a 375 99A. I bought the 22-250, SN RD1041, held onto it for a few years and sold it to fund some since forgotten project.
