As was mentioned and shown in the previous post I had to make an intermediate collet to accpet the cartridge case in the collet in the lathe spindle. The upper left picture shows the collet. No big thing to look at, but I was very pleased at the time (and still am, truth be known) with the accuracy and fine finish I could accomplish with my new lathe. Sorry, but I can't help it! Upper right is just another view of the shell holder.
While altering the brass cases for the 209 primer you have to put one in, drill it through, spot face it, and then take it out. I sure didn't want to have to stop and start the lathe that many times for each case. The supplimental collet was large enough around to get ahold of with the 5C collet opened, so I could pull it out and then put it back with a new case in it, while the lathe continued to run.

At left is loaded ammo ready to be fired. The sticky labels are there to allow even casehead expansion. The 32 guage case is close, but there is still a bit of windage between them and the chamber wall. A couple firings like that and the paper is removed and the case remains well centered. I opened the size die enough so it doesn't touch the casehead.
At right are the 4 targets shot with the new cartridge case on their very first outting! The bullet was the Lyman 457121 at 292grs. It dropped at .460+" so was just pan lubed. All the targets were 10 shot groups at 50 yards except for the Blue Dot, as they were used to get 'on' which required 3 rounds.
The sights on the carbine are typical, A little rounded nubby blade up front. The rear sight is 3 steps with a bitty short ladder with an elevator. You have a 'V' with the ladder down and a 'V' on the elevator. Rudimentary and NOT a 1000 yard setup. Also, the boolit at .460" is about .005" undersized for the groove. The brass while necked, goes into a chamber with NO neck, so the boolit has to do the centering and is engraved a bit. I'm totally blown away that they didn't go through sideways or just fly off on their own somewhere! At cleaning there was NO leading. Velocities IIRC ran about 1200 fps.
Options one of these days is to make a swage die to produce a slug with a .433" nose to fit the lands, and a .465" body. Maybe mashed up from a Lee 340gr 45 cal slug. Or a patched up .457" boolit to .465". Maybe cut a mould? Gotta accumilate some 'Round toit's' first.
Hope you enjoyed the process!
