Tested the Wickcliffe with 12ga FH case in a temperary chamber, just primer, 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. But 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
