I have a Bartlein CF barrel chambered in 300 W.M.
Sent it to be put in a cryogenic chamber to relieve any existing stress in barrel, upon unboxing I found the carbon cracked completely through in 2 separate spots.
Also sent a Proof barrel chambered with same reamer to have the same process done...
Going through blanks I ran across this 6MM blank, I believed it to be a rock creek. Got in touch with RCB today, and they said no barrel with that head stamp has ever left there shop. Anyone verify the maker?
Thanks.
