    Grab what you can use .. vises cat40?

    Try Craigs list. It may be a hobby rescue machine and you can get them to haul it away.

    Just to put that in perspective: that is 12 diameters, would you slot 6" deep with a 1/2" EM? Brave soul :-)
    Plunge milling to rough and then clean it up might work. Some things are just not easy.

    Think about how a dentist/dental tech removes machined material. Blow to suspend, vacuum to remove. Maybe rent a rotary (jackhammer compressor). Lots of air and some cooling from the loss in pressure.

    Nothing wrong with rimmed cases even in a bolt action. However, rotary magazines work rather well! Push comes to shove, buy a .303 and load down to 30-30 velocities. It would be a real pussy cat and...

    From the spacing of the pads I would assume that is a disc cap to dump high freq noise to ground. Unless things get erratic I wouldn't lose much sleep over it.
