Savage vs Marlin thread pitch

[cowboybart]

Are the thread pitches on the barrels the same on the Marlin XL-7 and Savage 110's??
The Savage 110 = 1.055" at 20 TPI
Savage 10 (WSM) = 1.120" at 20 TPI

What is the Marlin XL-7??
Are the barrels interchangable??

Is Boyd's making a thumbhole for XL7 yet??

The barrels are interchangeable if I remember correctly. I think the Marlin has a deep bolt face and causes you to either relive the face of the barrel or relieve the face of the bolt head accordingly to put a savage on a marlin.. A marlin on a savage I'm not sure but I think it is a headspace and go. Check on that.
