Nope.
A quick search at the Dixie site says there is no such thing as "CA0100", the Dixie number shown for the hair straightener molds in their 2011 catalog.
Ole' Turner Kirkland (the founder of Dixie Gunworks) is a rollin' in his grave again.
I'm sure the folks that are fairly new to muzzleloading don't have the foggiest idea about what a Hair Straightener bullet mold is and because they are no longer available I'll give a quick rundown for them.
Quoting from the Dixiegunworks 2011 catalog (p294),
"The Dixie Mould is designed with economy in view with as simple a mould as possible. Made without sprue cutter. Iron handles, heavy cast malleable iron and factory finished. Best for all round use.
In the 1950s, Turner found this tool in stores he visited as a salesman.
It was being used as a hair straightener by heating the head and pulling the hair between the flat faces. Turner realized it could be made into a bullet mould by "cherrying" the face to size. He located the original factory- still casting it as they had for over 100 years..."
It looks like a large cast iron pair of heavy duty sheet metal shears or giant scissors with a cast "loop" on each leg for the fingers to slip thru.
Rather than having cutting blades like scissors, they have a cylindrical end on each leg with flat faces to squeeze the hair as it is pulled thru them.
Back in 1987 they cost $12.95 and the roundball molds ranged in size from .28 to .875.
In the 2009 catalog the price had increased to $55.00.
I think their high price probably doomed them to extinction.
