Mike,
It looks as if the rim recess for the 8.15X46R was deepened to .065". In addition, the breach block easily closes with a .012" feeler gauge between the barrel and breach block. I wonder if both changes were made during the prior attempted restoration in an attempt to free the firing pin.
The barrel threads are 24TPI, so one turn of the barrel should be enough to correct the headspace. Then I'll have to deepen the chamber, recut the rim, recut the extractor slots and correct the forend hanger.
I've ordered a reamer from PTG as I have another 8.15X46R project to do after this one.
I'm sure getting my moneys worth from this rifle.
Otto
