Actually the 5mm RF was selling pretty well. It really eclipsed the 22 mag by far. but....always a but ya know...they had trouble with that 5mm blowing holes in the cases. Rather than fix the problem...the brass cases...they dumped the whole project...Remington already had a big project on their plate...the 700 Trigger. I was also told that much of the 5mm ammo w loaded by Remington subsidiary in Mexico . You can still sometimes find new made ammo for the 5mm and it's still better than the 22 WRFM or the 17 HMR. Still got a box or two of that Mexican ammo
