After a bit of research, it seems the major barrel manufacturers use a minimum of .150” from bore.
Example:
.308 + .150(x2) = min barrel size. .830-.608=.222
Divide that by 2 and ya get .111” depth of flutes. I just rounded down to .100”
Hope this helps someone

My first question would be who made the barrel? I've gone .125" deep on good blanks.

Doing the hoop stress math for a .15" wall on a .308" bore gives almost 85Kpsi barrel stress at 50Kpsi bore pressure. A .125" wall gives almost 94Kpsi stress. How close to the chamber are you planning to flute?
