John Lachuk was a long-time gunwriter. His work appeared in a number of publications. He was on the GUNS & AMMO staff roughly the same time Elmer Keith was. Much of Lachuk's writings were of a technical nature, often handloading-related. He probably did as much work with .44s as Keith did, but never enjoyed the popularity of other writers of his era.
Lachuk produced good articles, far better than most of today's gunwriters. I vaguely recall reading of some disparaging remarks Keith made about Lachuk, but don't remember the details. I'm pretty sure this came from one of Elmer Keith's books, long before the Internet, but then, Keith's version was only one side of the story.
