I'm looking to get a 29-30" Kreiger SS 1:8 twist in .243 bore with a HV contour to rebarrel a Rem. 700 to 6BR. I want to finish it to a 28" length. Most places don't stock them that long, most being 27" blanks. Does anyone know where I can find some without custom ordering and waiting for 3+ months? Thanks for any help.
