Okay, I was able to make some measurements. That would appear to be a long action base, Gary. Although my holes are 7/8" center to center, that measurement is about 3 1/2".
Thanks for the link, Feenix. That's definitely an option.
I called Winchester today (why do they not have a simple email link?) and they said that I have a standard short action and that any SA base will fit. This doesn't jibe with my gunsmith, so I wandered over to the gun store and talked to them about ordering a basic Leupold 1-piece base. It turns out that one of them has the same rifle. He said he spent a long time looking and buying bases and never did find one that fit. They were all too long, or too short. It would appear that this may be an intermediate length action, or at least the holes are lined up speshul.
Thanks you both for the ideas and the help!
