Here is a neat website I found dedicated to the new short magnums.

fishnfool,

Great site thnaks for sharing.

But all of the "new" cartridges are copy of Heavy Express cartridges nothing else.

Nice link. They have a great target that you can print out on that site. I can't wait to see if they start carrieing info on the WSSM's too.
