Precision Carbine 308 with 5R barrel...meh.

I bought a barrel off of a precision carbine. It was a new take off with about 40 cast boolits through it. Scrubbed it up and headspaced and off to the range with my favorite load. It was everywhere. I had my smith rechamber it and it was now out of round and messed up. I took it back and showed him the brass and he asked to have another shot. He called me the next day telling me the bore was oversized. So I got out my Starret small hole gauges and sure enough.. a new barrel that was .004 oversized from one end to the other. Worth looking at!

That's ridiculous! I don't even know how that can happen, unless it was contoured before stress relief after buttoning

I agree. I will qualify that I am a machinist and a precision grinder and I can inspect inspect things that a lot of people cant. By machining a go no go pin i can check rifle bores with odd numbers of flutes.

The reamer pilot was .2998 if I remember and it rattled around in the bore. The Smith who is well known had never seen it on a new barel.
