No brass to be found for the Sako.
Sure there is.......
http://www.z-hat.com/9.3x66%20Sako.htmI'm sure if a guy tried hard enough he could have 370 Magnum headstamped brass shipped from Canada or Europe
At $2 per piece I could pay for a new 9.3 barrel for the 9.3-375 wildcat!
Now, the Canada thing might be a doable plan. I have a buddy up there who might be able to square me away. Still, Opening up the chamber on an existing 9.3 barrel would be easy with any of these options.
