You need a five ton press to push this button down a barrel to form
the rifling. OK, what would be the highest strength steel i can get
for the pusher. I looked for HSS and couldn't find anything long
enough. looked for already hardened drill rod. It must be out there
but no joy so far.

My first barrels will be 12", want to do 16" in the future.
