Saw a Ruger No. 1 in a gunshop today that was listed as .256 Newton. It looked like it was factory produced, not a rebarrel/rechamber. Did Ruger ever make a No. 1 in .256 Newton?
Can the brass be made from something inexpensive? Did a quick search and found some that was recently made at about $2.00 per case. I seem to remember that Newton brass had a special head diameter.
Any other information about this?
