Okay now, the thread was great. It racked up a phenomenal number of views, and we had alot of fun with it.
Thanks, guys at the other forum....
If you're new to guns, no, these calibers do not exist, per se.
Let's let this one go gracefully into the sunset, to be forgotten, until some Governmant agency decides it needs a new caliber and commisions the venerable .43 Luger.
Well done, lads.
