I just got my 700 358W in A Wildcat stock back from the smith. I went with 22" on the bbl as I have shorter guns to use if needed. I thought that if I didn't like how it handled, I would get it shorter later, but I don't like anything shorter than 20".

The 22" feels fine. That 35cal hole takes out a lot of metal on the sporter contour so the balance is right there.
