Seems to me, I made up a .550 Mag. for a friend, a wildcat

ctg. collector in Spain - & 2 different ctgs. at that, one,

iirc, was necked & may have been on a .404 Jeffery or .577

case.

My memory of that bunch of wildcat cases is not good. I had

never heard of several of them before, but with pictures,

was able to make them.
