308 Chamber Reamer

[Danimal]

Anyone have a 308 finish chamber reamer that I can borrow? I need to take about 0.002 out on a new 416r barrel.

Lap your lugs instead, less chance of dinging the chamber.

The .002 was enough to prevent it from going into battery and I could not get it to wear without something to put back pressure on the lugs, so I chucked it up on my 4th axis and took the .002 off. Took forever to set up, but got it to just barely clear with a SAAMI round so I lapped it until it fit. Seemed to do the job and now I feel like the bolt is about perfectly matched with the barrel. Both were cheap parts bought on clearance, but now I think that they should work okay.

This was for a 308 AR based ultra light straight pull that I have been putting together out of spare parts. Should be pretty fun to shoot. It weighs about 6 lbs with scope.
