SPORTING CLASSICS also runs some. In fact a year or two ago they reprinted one of mine that first appeared in GRAY'S quite a while ago.
Even the "hunting stories" in older gun magazines often involved a product. I can remember one that appeared in GUNS & AMMO in the 1970's, where Elmer Keith hunted on a Texas game ranch, killing a blackbuck with a Wickliffe single-shot in .308 Winchester. He had to make a comment about how the .308 wasn't his idea of a big game round, so it obviously an assignment.
