    Rebating BR-case rims

    What is the easiest way to rebate the rims on the BR case down to PPC size?

    Lathe and a form tool. Very quick and easy.

    Does anyone sell

    a form tool for this operation? I have done a bunch of them with a borrowed tool but had to place a bond with the friend who loaned it to me and he ignored my request to grind one for me

    I second what Pete said...

    The tool is the hardest part...unless you have a tool and die shop and a 50x comparitor..

    Thank you all.

    I don't currently have a lathe. I've considered three options and would appreciate your input:

    1. Purchase a mini lathe.
    2. Purchase a purpose-built power tool for neck turning. You guys know what I'm talking about. Wondering if the form tool can be adapted to it.
    3. Buy the cases from Ron Hoehn and pay him extra (if he'll do it) to rebate the rims.

    Can someone tell me more about the form tool?

    Edit: I have a RB/LP/RE Grizzly II. Was wondering if someone would be willing to mail me a 30BR case with a rebated rim so that I could see if it will eject.

    Thanks,
    Greg J.

    I bought a micro-mini lathe last year adn while it is quite nice it lacks the refinements necessary to do good work. The lead screws in it are severely lacking and has no power feeds among other things. It is lite enough to lift around easily but is very limited . It did not come with a live center or chuck for the tail stock. A larger one would be better but I looked at what Harbor Freight offered in their showroom in Sout Carolina and was severely un-impressed. The next bigger size is too heavy to be portable easily.

    I rebated some BR cases in my Mini and it did not much care for the plunge cut one needs to make in the cases.

    I have a gear motor case turning lathe assembled by a friend and don't see that it could be used to rebate cases but I could be wrong. I guess given your options I would GLADLY pay someone to do mine if I didn't have a lathe. I am going to try to have a tool ground at a near by tool grinding shop. If I am able to get one I will continue to rebate myself. A much easier solution is to have the bolt face opened up. A SAKO extractor will pull .308 case heads if it is installed properly.

    Thank you for the input. I don't need it to be easily portable, but don't want to invest a ton of money, either.

    I've got that question into the Kelbly folks right now. I need them to look at it anyway because about 70% of my cases get the very lip of the case neck dinged on eject. The ding is minor and easily removed with my chamfer tool, but it's annoying.

    but not all of my cases get dinged and I simply expand them back out when I see them and keep going. The brass is resilient with regard to small stuff like this. I am assuming a flat spot vs an actual ding in the case neck?

    It's more like the very lip hit an acute-angle edge. I'll try to expand them out on my K&M mandrel.

    Thanks, Greg J.

    Just got an answer back from Kelblys. It says that I have to live with the dings, but that the bolt face can be modified. Woo hoo!

    You might try a lighter ejector spring to cut down on the dings.

    This is a pic of my form tool.

    Below is a pic of a Remington BR case without flash hole, a regular BR case, A rebated case, and a BR case rebated to 223 size.Before you form an opinion on the 223, Red Cornelison shot these for years without a problem.

    JMHO, but if you are going to rebate your own cases you should have the ability to grind your own tools. Otherwise you should be paying someone else to do the work for you.

    If you shop around you should be able to find a small lathe, such as a 6"Atlas, for only a few bucks. I bought one about 5 years ago, like new, for less than $100. You don't need a lot of tooling - a chuck, a tool post, and tool holder will let you do all the rebating and neck turning. I mounted mine on a piece of 3/4" plywood and it stores under a work bench and can be hauled out in minutes.
