Steve, I almost had one... I had an extra #1 in .300 Win. that I didn't need and a take-off M-70 Win barrel in .308. I took them up to the 'Smith and had him screw them together. By the time I got home, it occured to me that likely the 7.62x54 would clean up the chamber, (Especially if set back a turn or two.) So I called him back and instructed him to do so. Unfortunately, by the time he got to it, he had forgotten and I ended up with a .308 Win. At that point, I shrugged and said; Oh well, why bother. Ballistics are about same/same... But I thought that would have made a nice addition to my #1 collection as I have them in 6.5x54 M.S. .303 Brit, .30/40 Krag, and 8x57 Mauser. (And probably another one or two that I failed to mention...)
Cheers...
