Sorry, it’s 22”. I slept a few nights since I shot it last. Have less than 100 through it to break it in. It’s a varmint contour steel barrel.
 
I have a 18” Proof stainless steel barrel. Savage small shank with either a PVA nut or Zermatt nut, can’t remember. Less than 50 rounds on it. I used it during last years hunting season while waiting for my shorty carbon fiber barrel to come in. $250 shipped. If your interested send me a pm and I’ll get you some pictures this evening.

Did you end up selling that barrel? Muzzle threads? Zermatt nut? Thanks
