I have come into a stack of old magazines and love to browse them as most of the articles are as valid today as when the publication hit the shelves.
Today I picked up the "American Rifleman", April, 1981. Page 32 begins an article by J.B. Roberts Jr., "Cylinder throat fit" and features none other than a youthful Ed Harris and his swish new revolver. The article is still relevant also.
