I used to really like the American Rifleman, back when they had good DIY articles on 'smithing, like the 1950-70s. Now its just dumb ads for bogus "collector" 1911s and newer AR15 clones. Probably has something to do with nervous lawyers worrying about klutzes who tuned triggers down to 5 oz, and shot their foot off. Rifle Magazine put out a great book on tips and projects and I did a lot of them, including making my own bullet mold, and making a Low Wall conversion to 357 Maximum, AKA 38 Extra Long. Gave up doing color case hardening when I found out that bone and charcoal in a sealed pipe at 1400 deg makes cyanide gas....wife thought I was cremating the dog out back from the smell.
Actually, the bone and wood charcoal mix produces mainly carbon monoxide gas in the crucible at operating temperature, and a very small amount of phosphine gas during the quench. Cyanide gas is not produced.
