Gonna' be working late in the shop,....just playing catch up on a beer break.
Thought that was a C.Sharps,....based on the case colors,...a beaut, regardless, I love em' all ( other than the "Dark Valley Dagos")
Will be back, and elaborate ,....or maybe dig up some old writings on ceramic media,....
For the non,....suffice it to say that I don't CARE what the exterior of my cases look like,...as long as I can see a mirror polish INSIDE of em, and the exterior will feed and extract smoothly,...
If your cases have not been ANNEALED, ...QUIT TRIMMING !
ANNEAL, FIREFORM, and THAN check your case lengths.
...than maybe think about parking the dies,...let your SHOOTING do the sizing, and load "Old School"....whether Greasers or Slicks,....an awful lot of good shooting is going on with brass that NEVER sees anything but a powder compression die.
Later,
