Just a note of caution for anyone contemplating a re-barrel project.
When we replaced the barrel on the Mark 11G, the bolt face was trued as part of the receiver threading process and headspace set to a minimum.
By design, the firing pin has that raised portion on the nose which I assume is to prevent chamber rim damage if dry fired.
I have noticed a VERY faint impression where the F.P. has been making contact with the barrel - Too shallow to photograph clearly and no damage done.
I re-profiled the F.P. nose and there is clearance now.
Ignition is very positive since the re-build and I'm not anticipating any mis fires.
I phoned Savage Arms in the U.S. to order some spares the other night. First time I've done this - Great customer service and my order was processed with a minimum of fuss. Thank-You, Savage.
