Hi All,
I replaced my 30-06 dies with a used RCBS die set. I spent a bunch of time over Christmas working up a couple hundred pieces of Winchester brass. Sized, flash hole debarred, neck turned, etc. They looked good and chambered easily. Loaded up fifty with Lyman 311299 and headed up to the range. I had failure to fire on about a third of them. Looked like light pin strikes. They would fire if I recocked and fired again. Thought the bolt must be dirty and disassembled and cleaned it a5 home. Next trip to the range, the same thing. I noticed that some of the primers had backed out a bit. My next thought was a headspace issue. On closer inspection of the fl sizing die, this is what I discovered.
The previous owner ground off some of the die body length. So all the brass I prepped has the shoulders set back too far. This explains the misfires.
I hope to save all the brass I prepared by hopefully fireforming them back into place. The idea I have is to expand the neck with a .321 expander ball and then resize about 3/4 of the neck with the 30-06 die leaving a thicker neck at the shoulder junction the force the case back against the bolt face. Kind of like this.
This will chamber in my rifle, but the bolt is somewhat stiff to close. Think this will work?
