| Just put together a Rem 700 SA and Shilen short chambered barrel. Finished reaming,I thought I screwed up when the bolt freely fell closed on the go gauge. Didn't have a no-go, so I put a piece of cellophane tape (.002) on the head of the go gauge. Didn't close, what a relief. Oh yeah, it took me 8 full turns to get there. Today, since it's raining so hard and I've got a gun show to go to, I inserted a primed new piece of brass measured at -.002 (1.628). and fired it. After firing, I measured the primer protrusion at .002. I'm thinking this brings me to 0 headspace (1.630). Am I correct? Btw, this is a .308. Can anyone tell me if my method is flawed or will a charged case react differently? |
