Tested the Wickcliffe with 12ga FH case
in a temperary chamber to see if
hammer with beefed up spring would fire
bmg primers.I scalloped out the back
of the action so 12ga cases would feed
into the action and temp chamber
They fired ok. Bur the extra stiff spring
makes it hard to cock. We will have to work
on that.The original Wickcliffe
action that we want to scale up is tall
enough so that when breech block is
lowered the block clears the bottom
a 12ga rim when cases slide out of chamber.
So in the scale up we need to just add a
a little width for wider breech block,
and the bigger barrel thread, and keep the
sides thick for strength.Ed
