Damn! Another great idea I didn't patent! (Most folks don't know it but I thunk up the idea for mountain bikes back in 1976. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />)
Seriously, I've often wondered why they don't just make a case that starts at the same diameter as a belted case and then just run the sidewalls up from there. Not as much capacity as an Ultra mag or some such based on the .404, but it would definitely add usable space.
Even better, if I'm getting this right, you could clean up a lot of existing belted mag chambers if folks wanted to re-chamber to something based on the new case. You wouldn't have to change the bolt face nor modify the feed rails most likely.
I really think this is the most genuinely useful design to come up in hunting cartridges in a long time - far better than the Ultra Blasters with their excessive power and easier feeding than the short mags.
Good on Ruger and Hornady!
