So. Another one of my special projects took a flying leap backwards yet again today. I swear these things are one step forward; ten barrel rolls backwards.
Lesson learned though. Apparently one can finally size a straight wall case enough times for case head separation to occur.
On a high note, when you buy a new chronometer and suddenly remember these things need a tripod stand to work... In a pinch a TV table also works... But it's nothing when the first shot ruins the whole trip.
Now I'm off to figure how to remove the rest of the brass.
