[jayfry]

Hello, this is my first time posting. I just bought a new savage 110 fcp hs precision in 300 win mag. I'm upgrading to a shillen barrel but I need to know if my 110 has a small shank diameter or a large shank diameter? Can anyone help me with this?

It has a small shank only target actions and WSM, There are a few other stray models, anyway it is easy to tell by measuring small shank is 1.060" and the large shank is 1.112",
Both are 20 tpi.
