I ordered a new Wildcat reamer and Go Gauge from JGS on 8-19-14. They told me it would take 6 weeks to make it. They shipped it to me on 9-30-14, exactly 6 weeks.
I had Dave regrind a .308 Bisley for me a few years back, had the free bore shortened up to keep VLDs at magazine length and still be able to get into the lands. Turn around was just a couple weeks.
