faster and easier. Center punch the center, draw a circle 7/64" smaller
than the finished hole, prick marks on this circle 1/8" apart, use an air
drill and 1/8" stub bits and drill these holes, knock-out the slug,

clean-up
with a tapered reamer, finish with a sized reamer.

If you are really careful, a .243 winchester will make a nice
.308-315 hole in a frame. Might have to grind off a little crater wall

Maybe there is (or could be) a tool that could do this; small shaped charges
and something like the concrete nail thing that you hit with a hammer to set
off the cartridge.

Ayup..or the hole punch the rail road uses to shoot holes through the
web of rail road tracks. Uses a 45-70 cartridge and a penetrator.

off in job lots is hardly empire building, particularly when you give
them self determination under "play nice" rules.

for torturing the cat." Gunner
