I have a barrel in my lathe all threaded and ready to chamber, I'm renting a reamer. I was all set on a 6x45 Ackley but I'm thinking what else is out there. I know 6mm TCU but is there other options. It's a 13.5 twist and I have a bunch of old match bullets I'll be shooting. Reamers are getting pricey and I don't see myself ever cutting another so renting seems the way to go but I'm just kind of not inspired by this project.
