RP- I haven't forgot about the cartridges I have for you but I haven't had any need to get to SA yet. I still have them set aside and will eventually get them to you.
You may have found a 300blk or 280 by now but I'm pretty sure you haven't found any SuperMags yet.
If any member is heading your direction from Austin in the near future, please let me know.
You can always PM me with an address, if you want.
