Not to hijack a thread but there are a lot of 204cal "nerds" in this thread so....
I'm considering a 20x22arc, 20x22nosler or a 20x224 valkyrie. If I go gas gun the 20arc is out of the running. If I get a barrel spun up for my Howa mini then the 20x22arc is going to be my first choice. My smith is sending off dummy rounds for a straight neck down 20x22arc to get reamers "yes reamers" made. Will more than likely do a switch barrel set up on the mini.
I say all of that to ask this..... has anyone done anything like what I'm thinking about doing?
