I would like some guidance in the right direction. I am wanting to learn how to chamber, and profile a Barrel. I am wanting to learn this for my own personal satisfaction. Recently I purchased a few cheap .30 cal barrel blanks that I intent to use for learning, I do not expect to be perfect in my first few attempts. I also have no expectations that I can posibly ever build a barrel that is more accurate than anything commercially available. I own a Lathe that is adequate for me to learn with. I also know the very basics of using the Metal Lathe. I do have a lot of experience using a wood lathe, and so far my experience with the Metal Lathe is that the big picture concepts between wood and metal are similar, but with metal everything runs at a snails pace in comparison, and your tools are moved with knobs rather than by hand. So anyway, where to start. I know I need a Chamber Reamer, and a Finish Reamer. I am thinking that I would like to ultimately work with something like .300 AAC Blackout, .30-30, or maybe .308. I don't want to mess with anything larger than .308 though. I am also thinking it might be best to work with a straight walled case as my first attempts, and then I can always reuse the straight walled barrels to do a tapered round by triming them down some. Anyway could someone offer some guidance as to what tools I need to buy, and where to start this learning excercise?
