I bought on Ebay a new bolt and carrier. As I explained in the article I wrote, I thought the original bolt had been shortened so I needed to set the barrel back to correct a headspace problem.

But the “new” bolt I just received is actually a few thou shorter than the original bolt! I can’t correct this with longer toggles as the two shoulders of both bolts are hard and fast against the receiver and can not be pushed any more forward unless some material is removed from the bolt.
The carrier fits perfectly so it isn’t that the frame stretched in this area. Strange…
Seems the only way I’m going to be able to correct is to solder a disc to the front of the bolt and machine and drill a hole for the firing pin.
Onward and forward!!
How much excess headspace do you have?
The shank length of a 73 should be .709, figure in case head thickness of .065 so you should have a measurement of .774 from the receiver face to the bolt.
What are you measuring?
At four different points around the face of the action:
.790
.787
.796
.785
The face of both bolts are off square
(The new bolt I just received is a few thou shorter.
I turned my shank to .725 in length
Looking at it again, if I solder a disc to the bolt face, I’ll have to make a new firing pin and extractor. The extractor cut fits the bolt face and engages the cartridge rim perfectly.
Drop me an e-mail at [email protected]
I may have some thoughts before you go soldering,cutting etc
