I think the original barrel was 14. I swapped into the rifle about 12 years ago, then after I bought a Lyman Bore Cam a couple of years back, and discovered the bore was pitted from chamber to muzzle. That would explain why the rifle rarely shot under 3/4 of an inch. I had Pac-Nor rebarrel it with a 1:12 barrel 24 inches long. Had I been aware of the availability of the 70-grain Accubond I would have gone with about 1:9, I think.
