I just took possession of my very first 6ppc. My rifle is an older rifle but very nice. it is a Hall action on a McMillan stock and it came with a couple barrels. One krieger and one shilen ratchet twist. The question i have is on the shilen. The marking as you will see have the numbers 891 then a 262ND. I know what the 262nd is referring to but the 891 i have no clue. I also asked this over on 6mmbr but i havent gotten any help, so i thought maybe someone over here might know. I appreciate the help!! Thanks Lee
