I am thinking of re-configuring a couple rifles, mothballing my 300whisper& making a 308 out of it, its built on a flatback long action& I need to swap bolt heads. Midway has the new style bolt heads, so I know the firing pin hole is smaller, can this be reamed, or do I need to swap firing pins?
It looks like the ejectors may be different. What else?
Just to get it started, I would think that it could be reamed but I have no knowledge of the process.
It can be drilled out.
Better solution it to swap to the smaller pin and smaller hole bolt head retaining pin. The smaller hole in the retaining pin keeps it from breaking in half at the most inconvienient time.
Shank on 110 bolt head is 1/8'' longer than 10
