While reading some other threads here dealing with dead cartridges, I started to wonder "what are some really hipster handgun cartridges I can get in to?" I'm already a faithful devotee of the 10mm Auto, but this isn't hipster enough to qualify. Why? It's useful, it fills a niche that other cartridges don't. In this case it's a semiauto intended cartridge with some serious power. A real hipster cartridge needs to be the following: obscure, no factory loads available, "used to be cool", and kind of pointless. By kind of pointless I mean it shouldn't have any significant advantage over other commercially available rounds. For example .41AE. Barely better ballistics than 40 and eclipsed by 10mm. So I'll start. 9mm Largo I think borders on hipster cartridge. No specific brass for it, but you can use 38 super brass so maybe it's not hipster enough. What are your guilty pleasure hipster rounds? Which hipster calibers should I stuff magazines full of into my skinny jeans that are 2 inches too short?
