savage has a working system with there barrel and bolt relation right?

so why would it be the savage bolt that is wrong for the action when you introduce a barrel not intended to be used on the savage action?

why can it not be that marlins barrel (or maybe just that one even) is not a perfect match for a savage action?
( not saying you can't, just was not built with that in mind)

can you say that the chamber was cut right to start with? not a factory error?

what is the spec depth of a marlin bolt head?
