I recently ordered a 12 F Class in 6br and anxiously waiting for it. In a discussion with a buddy a couple days ago, he mentioned that a barrel that uses a nut, instead of a shoulder, would only have a 1" barrel max. I know that the Target Action takes a large shank barrel, but what is the size of a bull barrel for it?

And, is the OD of the action larger than the standard 12 series actions?

Just curious.
Thanks in advance,

Richard
