Mine .223 is a 1/10 I purchased a couple months back. It stabilizes a Sierra 69 gr SMK just fine. I wished they had kept the 1/8 twist and would consider selling mine for a new 1/8 left-handed stainless T3.
To add, it frustrates me when a vendor advertises something that they don't have. This was after asking for confirmation on two separate occasions. Verify with a picture if a vendor says they have a 1/8 twist. Some "reputable" vendors don't know what they have.
