Any recommendations on /k/ approved westerns?

I love old school gun nerd shit that isn't fuddlore or myth. Accurate technical discussions and scenes in movies on firearms of the time, seems to be a rarity in films but it does occur. I found an archive of some kind of gun newspaper/magazine from the late 1800s a few years ago that had lots of 1800s /k/ talk that wasn't just a exaggerated shakespearean sales pitch like most gun literature from the time. For the life of me I can't remember what it was called. Fascinating stuff learning about gun nerdery of the late 1800s
