.338 bolt barrel blanks in a 1:3 twist?

[Donneric]

I've been reading about the 8.6 Blackout in an AR 10 configuration. But in a bolt rifle it reads way better for suppressed loads. My initial look into 338 barrel blanks with 1:3 twist yields a big fat zero. Am I missing something? I don't even see gas barrels for it. Hoping to hear I just havnt looked hard enough.

1:3 twist? I initially thought that was a typo but then I did a little reading on the 8.6 Blackout. Interesting.

Faxon has barrels.
