Bushing blocks ejector

I thought my .260 Rem bolt bushing job came out about perfect. .480 Inside diameter on the bushing, but the bushing blocks the ejector hole.

Ejector is .140. I can get the back side of a .128 drill bit into the ejector hole, but .134 doesn’t go.

What should I do? Should I open it up more?

What’s the max for a .473 bolt face round like the .260 Rem? I'll only get .001 clearance re-opened for each .002 I open the face, right?

Or should I turn down the ejector head?

Thanks,
Steve
 
Steve,

Couldn't you mill or even dremel out the area where it overlaps the ejector? Just relieve a small notch?

I can't see any gain in turning down or even stepping the ejector. Sooner or later you'll want to change it or even plug it....... and having to fiddle with the bushing just seems a pita.

Part of the process when bushing the bolt face is opening up the ejector area in the bushing. Apparently you have opted to change the extractor to something other than standard. I normally set the bolt up vertically in the mill to use a small (.156") end mill to open up the area needed and then drill with the .144" number drill to ensure there is not bind in the ejector.
 
Thanks for the replies.

FYI, yes I cut the bolt for and installed a Sako medium extractor.

When you drilled the hole for the spring and plunger, what did you use for a setup; you could have relieved the ejector hole at the same time.

This is how I do it.
