Forming Cases and other things

[Kurt]

Well the cases will shorten when they expand. Even a full length sized case will shrink some when fired.

When I formed my .44-90 bn cases from .44 basic I filled the case with junk mixed powder and gave it heavy compression with three card wads and fillet it with corn meal again and compressed it and fired them like blanks the first shot and that did a good job, but I did not have to blow out the case walls like you did. I just formed the shoulder and neck. I also reduced the loaded round case neck some and left it long and let it blow into the throat lead. This worked fine for me and it gave me a point where to trim the case a little long for the second firing so they weren't short. A little more work but the cases turned out the way I wanted them.
