I love Lindybeige’s channel; he’s got a lot of practical how-tos and whys for writers of adventure stories and historical fiction. Here’s a practical guide to revolvers, thoroughly dispelling a lot of spaghetti western myths. I’ll just put in that in the Wyrd West, a lot of legendary old firearms have been modified by gnomes or simply work better by magic. (Yeah, it’s a cheat, but the stories are fun, so I make no apologies!)
