A question posed on many an occasion.....so I did the math considering the UNF thread geometry. The last 3 columns provide effective sidewall 'meat' for the corresponding family of cartidges. Interesting to note that the Savage standard barrel thread root diameter is greater ;D than the larger diameter Rem/Wby barrel as a result of the finer (shallower) Savage thread pith;

Barrel dia" OD(mm) root '08/'-06 Mag WBY

Sav Std. 1.055 26.797 25.239 6.639 6.104 5.229
Sav wsm 1.125 28.575 27.017 7.528 6.993 6.118
Rem/WBY 1.0625 26.9875 25.040 6.540 6.005 5.130

You can read from this that theoretically a wby magnum in a STANDARD savage barrel leaves more steel around the cartridge (note this disregards action thickness) than a Weatherby MarkV in 378 family chambering.
