Jrmartin1964,
They do not exit. First off if you will read my #17&19 posts you will see the forms the Keith had.
The bullet you posted with the hp and GC is a Ray Thompson design not a Keith. The Ray Thompson design came way after the Keith. The Keith was only in solid nose, hollow point and hollow base design.
No gas check.
Go back and read my post #17&19.
If you know of a Keith from Lyman with a GC and a HP on the same bullet either,show it or let us know where we can see it where it is noted that is is a Lyman mold and not a custom.
