So that would mean you can't properly headspace a Savage barrel on a Marlin unless you lathe some material off the chamber face. The Marlin bolt hood would hit the Savage barrel before it headspaced properly. The Savage can utilize more chamber ramp for better feeding.

Big thanks to Bruce, nice pics. The measurement of .140" depth, is that within .001" or .010" ?
The Savage depth is approx .115" There is a slight dish shape from tumbling and I find the ones that measure deeper often have more dish, hence the deeper measurement. Say .115" - .117" normally.
